She conceived again, and bore a son; and she named him Onan.

Judah said to Onan, “Go in to your brother’s wife, and perform the duty of a husband’s brother to her, and raise up seed to your brother.”

Onan knew that the seed wouldn’t be his; and when he went in to his brother’s wife, he spilled it on the ground, lest he should give seed to his brother.

The sons of Judah: Er, Onan, Shelah, Perez, and Zerah; but Er and Onan died in the land of Canaan. The sons of Perez were Hezron and Hamul.

The sons of Judah: Er and Onan. Er and Onan died in the land of Canaan.

The sons of Judah: Er, and Onan, and Shelah; which three were born to him of Shua’s daughter the Canaanitess. Er, Judah’s firstborn, was wicked in the sight of the LORD; and he killed him.
