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

Then Judah said to Onan, Go in to thy brother's wife, and fulfil to her the brother-in-law's duty, and raise up seed to thy brother.

But when Onan knew that the seed should not be his own, it came to pass when he went in to his brother's wife, that he spilled it on the ground, in order to give no seed to his brother.

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

The sons of Judah: Er and Onan; and 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 the daughter of Shua the Canaanitess. And Er, Judah's firstborn, was wicked in the sight of Jehovah; and he slew him.
