3She conceived, and bore a son; and he named him Er.
4She conceived again, and bore a son; and she named him Onan.
5She yet again bore a son, and named him Shelah: and he was at Chezib, when she bore him.
6Judah took a wife for Er, his firstborn, and her name was Tamar.
7Er, Judah`s firstborn, was wicked in the sight of Yahweh. Yahweh killed him.
8Judah 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."
9Onan knew that the seed wouldn`t be his; and it happened, when he went in to his brother`s wife, that he spilled it on the ground, lest he should give seed to his brother.
