Genesis 38:9-11

Names of God Bible

⁹ But Onan knew that the descendant wouldn’t belong to him, so whenever he slept with his brother’s widow, he wasted his semen on the ground to avoid giving his brother a descendant. ¹⁰ What Onan did angered Yahweh so much that Yahweh took away Onan’s life too.

¹¹ Then Judah said to his daughter-in-law Tamar, “Return to your father’s home. Live as a widow until my son Shelah grows up.” He thought that this son, too, might die like his brothers. So Tamar went to live in her father’s home.
