Lectures On Genesis And Noah’s Seven Laws



Introduction-1/ The Seven Commandments’ list




1: The USA Congress’ Recognition


 The front page of this internet site posts the USA Congress’s recent resolution, recognizing the Seven Laws of Noah as the “base for the moral fabric of our great nation” and signed by President GW Bush, 3-26-91.

By this declaration, the USA has become the first and only nation to publicly honor the Seven Laws of Noah as its moral guidance. Let’s pray that other nations would follow suit.

Let’s highlight some words of  the Congress’ declaration:


Whereas Congress recognizes the historical tradition of ethical values and principles which are the basis of civilized society and upon which our great nation was founded

Whereas these ethical values have been the bedrock of society from dawn of civilization when they were known as Seven Noahide Laws

Whereas without these ethical values and principles the edifices of our civilization stands in serious peril of returning to chaos

Whereas society is profoundly concerned with the recent weakening of these principles that has resulted in crisis that beleaguer and threaten the fabric of civilized society…


Here the USA Congress is concerned that without the Noahide Laws our society would face serious peril of chaos, inferring to Noah’s Flood.

It behooves every American citizen to be familiar with and follow the Seven Noahide Laws.


The outline of our course

We will first discuss the Seven Commandments as a group. We’ll ask: Who gave them, where and when? What separates them from Moses Ten Commandments?

Then we will focus on the individual Commandment one by one.  Over the years I’ve learned that the best way to comprehend them is to follow the Book of Genesis, chapter by chapter.  The Book takes you into a journey from one Commandment to the next.  It seems that Moses wrote Genesis with the Commandments on his mind.

The ideas presented in this class are drawn from the vast sea of the Talmud,  the Torah Commentaries, the Jewish liturgy and prayer books, and the services practiced in the Holy Temple in Jerusalem.  These ideas therefore represent mainstream Judaism, some thousands years old.

2: Commandments for all Mankind


 What are the Seven Commandments?

The Seven Noahide Commandments are set of moral principles that preceded the Ten Commandments of Moses given to Israel  on Mt. Sinai.  They were given to Adam and Noah, and then incorporated into the Ten Commandments.  While the Ten Commandments were given to Israel as part of becoming a “Holy Nation of Priests,”  the set of Noah’s Laws were given to All Mankind.  Some of the Ten Commandments therefore do not pertain to the Nations, such as observing the Holy Sabbath.

The Talmud presents several lists of the Commandments, some including eleven rather than seven.  The  most commonly used  list, however, is the following list of Seven:








Note that every Commandment is in a huge  “headline”  that splits into many sub laws. How large? Most of the Talmud (Nachmanides).  It  would certainly take a lifetime to master these Seven Laws in details.

For instance– it s said that the Patriarch Jacob -who is considered a “child of Noah”  ( Maimonides) – spent 16 years of studying the Seven Laws of Noah in the Torah Academy established by Noah’s firstborn son, Shem ,near Jerusalem,   (Abraham, Isaac and Jacob are said to have studied under Shem, as we’ll  learn in due course)

It should be noted that the late Lubavitch Rabbi in NY did plan to open a Yeshiva (Torah Academy) for Non Jews to study the Seven Commandments of Noah for two years.  It shows how large the volume of the material is.


A necessary moral code for a decent society

It has been said by many authorities that the the Seven Commandments of Noah comprise the bare necessity  for any decent human society to exist. No society can survive for long without them.


Who gave Mankind the Seven Commandments and where?

The  term “Commandments” infers  that they were given to Mankind by an  authority.  The Torah ( Bible)  tells us that God gave them to Adam and Eve in the Garden of Eden, before they were driven out to live on real Earth.

The Talmud finds a hint for that in the verse verse: “And The Lord God Commanded on The Adam saying…from the Tree of Knowledge Good and Evil you shall not eat!” (Genesis 2)  Here the word “Commanded” is superfluous.  It could have simply said : “He told Adam…”   Hence the Lord God Commanded on  Adam not only the prohibition to eat the Fruit but also gave gave him Six (of the Seven) commandments, namely IDOLATRY, ADULTERY, THEFT, JUSTICE and BLASPHEMY.

After the Great Flood, God added to Noah the Seventh Commandment,  as  a part of the Rainbow Covenant.  It prohibits the consumption of blood and a  limb torn from a living animal.  It was given to teach Mankind not to be cruel, and to overcome our bloodthirsty heart and to stop BLOODSHED, as we’ll learn in due course. .

Natural Moral Code?

Since most of the Seven Laws of Noah can be traced in the laws of every human civilization, many scholars regard them as a set of “Natural Code of Morality,” a step in Man’s evolution.  It is as if these Laws are somehow engraved in our genes and brains as humans.

The Torah tells us that these Laws were given to Adam and Eve in Eden (apart from the Seventh) which is regarded as Man’s cradle. Adam and zeve lived there prior to be driven ot to live on Earth.  Everything that was given to them in Eden, therefore, are engraved in our psyche.  No wonder that these Laws seem Natural.

In fact, the notion that these Laws are imprinted in our psyche infers that no one may claim being unaware of them. No one can escape responsibility of abiding by them.  No one may claim that he or she is unaware of the prohibition to commit murder!


.Why after Noah rather than after Adam?

Since six of the Seven Laws of Noah were given to Adam in Eden, why wouldn’t we name them after Adam?

The answer is that after the Great Flood, Noah and his beautiful wife Naama (we’ll learn about them!) replaced Adam and Eve as Mankind’s parents.  We  are all considered Children of Noah, Bnei Noah, whether were are Jewish, Christians, Muslims or any other faith. .

Moreover, we are all named after Noah since we still live under Noah’s Rainbow Covenant. Transgressing Noah’s Laws  would therefore bring on us back the Flood! 


3: The Order on the Commandments on the List 


There are several lists of the  Seven Commandments using  different orders.  In our class we will   follow the most accepted one listed above. The reasons behind choosing this particular order of the Commandments are as follows

Legal  reasons:

The three laws at the top:  IDOLATRY, ADULTERY and BLOODSHED are often bound together, for they incur (potentially) the worst penalty- execution by human court.  The rest of the Commandments incur monetary retributions only.      .

Another reason- the three Commandments at the  top demand that we would surrender our lives rather than violating them.

Thus if  forced to sexually violate one’s family- mothers, sisters, daughters, granddaughters – one is expected  to die rather than comply.

Same is true for Bloodshed.  If forced to commit a murder, one should die rather than comply. .

Yet there is  a difference here between Israel  and the Nations.  Israel is obligated to surrender our lives rather then comply, while the Nations are expected and rewarded for it yet not obligated. As a rule , Israel is treated more harshly and severely than the Nations

  Logical reasons:

There is  a wisdom behind the order of the Commandments on the list. They present a cascade where one sin follows or brings the other . Thus

IDOLATRY  comes at the very top – since without believing in G-d, there is no meaning for the Commandments.  In fact, without fearing God, who or what would hold you back from violating the rest of the commandments?

ADULTERY follows – for if you don’t fear G-d, what would hold you  from having an affair with another person’s spouse?

BLOODSHED  follows next for having committed ADULTERY, wouldn’t you expect the offended spouse to chase  after you with a knife?  And wouldn’t you try to get rid of the spouse first? .

THEFT  often follows for once you’ve stolen someone’s spouse, wouldn’t you also steal his/hers property?

INJUSTICE follows, for having committed all the above, wouldn’t you attempt to cover  up your deeds?

 BLASPHEMY follows for if society would permit all the above you’d certainly come to curse your mother, your father and your CREATOR for having brought you to this world.

A sad case as a demonstration.

The cascade of sins predicted by the Seven Commandments is often observed in real life. Here is a sad case:

A decent member of our Orthodox Jewish congregation had a wife whose believe in God was light (IDOLATRY.)

One day her husband – a pillar of faith in our community- return home earlier than usual catching his wife with her lover on the sofa at his home (ADULTERY)

He later said that had he had his gun on him, he would have shot them both on the spot (BLOODSHED)

Moreover- he then discovered that for years his unfaithful wife had embezzled his resources to support  her lover’s different failing businesses  (THEFT)

Taking his wife to the civil court asking divorce, he had to confront the shrewdest  lawyer his wife had hired.  This lawyer smeared the husband so badly that he lost his properties and the custody over their children (INJUSTICE.)

Despite his deep agony, the poor husband overcame his temptation to curse G-d (BLASPHEMY) and  remained loyal to the community. .


Another example: The story of the Great Gatsby

At first, the Great Gatsby makes a fortune by wicked, godless ways (IDOLATRY)

Then the Great Gatsby discovered that  his former sweetheart was living across of him by the lake.  She is now married. The Great Gatsby attempts to attract her by conducting lavish parties in his fancy house.  He manages to entice her into making love with him (ADULTERY.)  Her  hurting husband planes to have him killed (BLOODSHED) and even steal his money (THEFT.).  The frightened unfaithful wife trying to escape and the car hits a woman.  The Great Gatsby attempts to cover up her crime (INJUSTICE) but is finally shot dead by the dead woman’s husband.   , .


These stories are so compelling because they follow the cascade of sins inherent in our hearts – and  predicted by the Primordial Six Commandments of Adam. .

We are programmed to be tested by them

So entrenched are the Six Commandments of Adam in our souls that it seems we are destined – or programmed- to be challenged by them one by one, day by day, all our lives.

As we wake up every morning we should recall that we are about to encounter these Commandment during the coming day.

We should pray to our CREATOR that He would give us strength to overcome the Serpent and not stumble over IDOLATRY, ADULTERY, BLOODSHED, THEFT and BLASPHEMY.


4: Negative and Positive Sides of the Commandments

The Seven Commandments given to Adam and Noah tell us what NOT to do.  They are Prohibitions or Negative Commandments. Thus they say

I: Thou shall not commit IDOLATRY

II: Thou shall not commit ADULTERY

III: Thou shall not commit BLOODSHED

IV: Thou shall not commit THEFT

V: Thou shall not commit INJUSTICE

VI: Thou shall not commit BLASPHEMY

But as a rule, every Negative Commandment also implies a Positive aspect telling us what To Do.  Thus

I: IDOLATRY implies that we should believe and worship only GOD

II ADULTERY implies that we should cherish marriage and raise a family

III BLOODSHED implies that we should cherish Peace and control our rage

IV THEFT implies that we should support private ownership and cherish honesty

V INJUSTICE implies that we should establish righteous courts and elect honest judges

VI BLASPHEMY implies that we should support holiness

Thus the Negative and the Positive Commandments are two sides of the same coin.  Yet there is a difference:

While the Negative sides are expressed  explicitly as open Commandments whose violation incur  punishment (by human court or by Heavens)

 The Positive sides are only indirectly implied, without open specific retributions

This distinction is important because the Negative aspect is mandatory  and incur retributions.   The Positive aspect in contrast is only ‘expected’ or ‘recommended’  without punishments.

The Negative ones are enforced,

The Positive ones are only recommended (and rewarded).

Most authorities discussing the Seven Commandments do focus therefore on the Negative side solely,  saying  little if anything about the Positive aspects.

For instance– Describing ADULTERY, most books would focus on the forbidden sexual relationships.  A man should not cohabit with his close family members nor with another person’s spouse.   Yet these books  would say nothing about marriage, or how to bring holiness into our family life.

The same is true for IDOLATRY.  Most authors elaborate on the the Negative side – the laws prohibiting idol worship; yet say nothing about the Positive aspect – how to recognize and worship the True God .

The same goes for BLOODSHED.

 INJUSTICE is different . In addition to the Negative side , there is an open discussion of the Positive side- on how to DO JUSTICE. The Commandment obliges all Nations to erect righteous courts in every District and Town, to appoint qualified and  learned and hones Judges and to set up dedicated police force.

For Israel, the Positive side of every Commandment becomes an obligation, punishable to human court or by Heavens. Again, Israel is treated more harshly and more demanding way

  In our classto Noahideswe will emphasize both the Negative and the Positive sides of each Commandment- with a difference. .  The Negative side is presented as obligatory, while the positive sides as expected and rewarded but not obligated.   .


5: Noah’s  Seven incorporated onto Moses’ Ten Commandments


Five  of Noah’s  Seven  Commandments were incorporated into Moses’ Ten Commandments of Sinai.  Thus-

Noahide Laws…………………Moses’ Ten Commandments

I: Idolatry………………………..II: Thou shall have no other God over my Face

II: Adultery………………………VII: Thou shall not commit adultery

III: Bloodshed……………………VI: Thou shall not murder

IV: Theft………………………….VIII: Thou shall not steal

V: Justice…………………………IX: Thou shall not bear false witness.


Noah’s VI – BLASPHEMY – was also told to Israel ( You shall not curse God, Exodus))

Noah VII – Prohibition to consume Blood and a Living Limb- was also  told to Israel

By repeating Noah Commandments to Israel, Moses made them applicable to both Noahide and Israel

Those Commandments that Moses told only to Israel, apply only to Israel

Examples: The Sabbath’s Laws, The Yom Kippur or Passover Laws, the  dietary kosher laws and more.

Two Signatures 

All peoples and Nations listen to Moses

But Modest Moses tells the Nations – to Noah’s Children – to listen also to their Father Noah.

Hence the Nations abide by a Commandment  only if it carries  two  signatures – of  Moses and Noah .

A Commandment carrying only Moses’  signature, without Noah, apply  only to Israel


 6: Can Noah’s Seven Commandments be enforced?


As a rule, the “Noahide Nations” may force each other to abide by Noah’s Seven Commandments (Maimonides).

The logic is simple-  Humanity can’t tolerate a community that does not abide by IDOLATRY, ADULTERY, THEFT, INJUSTICE and BLASPHEMY.  These laws form the basis of any decent human society (USA Congress) .

Israel– a special Child of Noah –  may likewise enforce the Seven Commandments of Noah on Noahide  Nations. But Israel may NOT enforce the specific Commandments given by Moses to Israel, on other Noahide Nations.  Israel may never “convert”  other Noahide Nations by force to become members of Israel . .

For instance: before entering the Land of Canaan, Joshua sent scrolls to all the inhabitants of the Holy Land demanding  them to accept and abide the Seven Commandments of Noah .  Those who responded positively he left in peace. Those who continued to practice human sacrifices to the Molech and “sacred prostitution” he either chased out or eliminated.  And ever since then all the inhabitants of the Holy Land are required to abode by Noah’s Laws.

 Having discussed the Seven Commandments as a group,

let’s discuss them next  one by one.





6: Historical impact of Noah’s  Commandments

The impact of the Seven Commandments of Noah on history is immense.

Thus, Christianity was born when St. Paul was ‘dispatched’ by the elders of the nascent Christian Jewish sect in Jerusalem, to teach the gentiles the Seven Laws plus the “good news of the coming of the Messiah” (see Acts.)

Islam, centuries later, was born when Jewish tribes in the city of Yathrib (now Medinah, north of Mecca) opened their schools to the local pagan Arabs, teaching them the Seven Laws of Noah, and other stories of the Bible. The rest is history.

In fact, other major religions like Buddhism and Shintoism, share similar moral principles with Noah’s Seven Commandments.
