When Noah awoke from his drunken stupor he learned what his youngest son had done to him.

Cain had marital relations with his wife, and she became pregnant and gave birth to Enoch. Cain was building a city, and he named the city after his son Enoch.

When the dove returned to him in the evening, there was a freshly plucked olive leaf in its beak! Noah knew that the waters had receded from the earth.

And Adam had marital relations with his wife again, and she gave birth to a son. She named him Seth, saying, “God has given me another child in place of Abel because Cain killed him.”

But Onan knew that the child would not be considered his. So whenever he had sexual relations with his brother’s wife, he withdrew prematurely so as not to give his brother a descendant.
