And she conceived again, and bore a son, and she called his name Onan.

And Judah said to Onan, Go in to your brother's wife, and marry her, and raise up seed to your brother.

And Onan knew that the seed would not be his. And it happened when he went in to his brother's wife, that he spilled on the ground, not giving seed to his brother.

And the sons of Judah: Er and Onan, and Shelah, and Pharez, and Zarah. But Er and Onan died in the land of Canaan. And the sons of Pharez: Hezron and Hamul.
