Genesis 2
Verse 18: It is not good for, etc.
So that they [the heretics] not claim that there are two dominions, G-d, above, is alone, without a mate and this one [man], below without a mate.
A helper for him.
If he is worthy then [she is] a helpmate, if he is not worthy then [she is] opposite him, to fight him.
Verse 19: Formed from the ground.
This "creating" is the same as "the making" which was stated above: "And G-d made the animals of the earth, etc." However, here it comes to explain that the fowl was created from the swamps. Since above it stated that they [the fowls] were created from water and here it states that they were created from the earth. Also, it teaches you that immediately, on the day they were created He brought them to man to call them by name. According to Aggadah, the word {Hebrew Ref} here has the meaning of dominating and subjugating as [in the verse:] "When you will besiege a city;" [accordingly, here it means] that He subjugated them under the domination of man.
Whatever the man called [each] living creature, etc.
You must transpose [the words] and explain it: All living souls that were given a name by Adam will retain that name forever.
Verse 20: But the man did not find a helper... Ad-noy El-him caused unconsciousness to fall.
When He brought them [the animals] before him He brought the male and female of each specie. [Adam] said: They each have a mate but I have no mate; immediately: "And G-d put [Adam]..."
Verse 21: Of his ribs.
[Has the literal meaning] from his sides as [in the verse] "The sides of the Tabernacle." This [coincides with] what we said: that they were [first] created with two faces.
And closed-over.
The place of the cut.
And he slept...and He took.
So that he not see the piece of flesh from which she was created and be repulsive to him.
Verse 22: [He] built.
Like a building, broad at the bottom and narrow at the top so that she can carry the child. [Just] as a wheat silo which is broad at the bottom and narrow at the top so that its weight not be a strain on its walls.
[He] built the rib ... into a woman.
[Meaning:] so that it should become a woman as [in the verse]: "And Gidon made it to an ephod," [meaning] so that it should become an ephod.
Verse 23: This at last.
This teaches that Adam attempted to find [a mate] amongst all the animals and beasts and he was not satisfied with them until he discovered Chavah.
This shall be called Woman, for from Man, etc.
[The words {Hebrew Ref} and {Hebrew Ref} ] have the same root. From this [we derive] that the world was created with the Holy Tongue.
Verse 24: Therefore, a man shall leave.
The Divine Spirit is saying this prohibiting to the "sons of Noach" forbidden marital relations.
One flesh.
The child is formed by both [parents] thereby becoming unified as "one flesh."
