1 Chronicles 2:3

²There, Judah saw the daughter of a certain Canaanite man named Shua. He took her, and went in to her. 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. 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 LORD’s sight. So the LORD 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 offspring for your brother.” ⁹Onan knew that the offspring wouldn’t be his; and when he went in to his brother’s wife, he spilled his semen on the ground, lest he should give offspring to his brother. ¹⁰The thing which he did was evil in the LORD’s sight, and he killed him also.

¹⁹The sons of Judah: Er and Onan. Er and Onan died in the land of Canaan.

¹²The 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.

⁵Of the Shilonites: Asaiah the firstborn and his sons.
