Genesis 38:9-11

Revised Geneva Translation

⁹ And Onan knew that the seed would not be his. Therefore, when he went in to his brother’s wife, he spilled it on the ground, lest he should give seed to his brother.

¹⁰ And it was wicked in the eyes of the LORD, that which he did. Therefore He killed him also.

¹¹ Then Judah said to Tamar, his daughter-in-law, “Remain a widow in your father’s house until Shelah, my son, grows up (for he thought, “Lest he die, just as his brothers.”) So, Tamar went and dwelt in her father’s house.
