And again she gave birth to a son, and he gave him the name Onan.

Then Judah said to Onan, Go in to your brother's wife and do what it is right for a husband's brother to do; make her your wife and get offspring for your brother.

But Onan, seeing that the offspring would not be his, went in to his brother's wife, but let his seed go on to the earth, so that he might not get offspring for his brother.

And the sons of Judah: Er and Onan and Shelah and Perez and Zerah: but Er and Onan had come to their death in the land of Canaan; and the sons of Perez were Hezron and Hamul.

The sons of Judah, Er and Onan: and Er and Onan had come to their death in the land of Canaan.

The sons of Judah: Er and Onan and Shelah; these three were his sons by Bathshua, the Canaanite woman. And Er, Judah's oldest son, did evil in the eyes of the Lord; and he put him to death.
