Genesis (Part 71)

That very day Abraham and his son Ishmael were circumcised.

Genesis (Part 70)

Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?

This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised.

No longer shall your name be called Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations.
