Genesis 38:3-7 ▼

3 So she conceived and gave birth to a son and Judah named him Er.

4 Then she conceived again and gave birth to a son and named him Onan.

5 Again she conceived and gave birth to still another son and named him Shelah. It was at Chezib that she gave birth to him.

6 Now Judah took a wife for Er his firstborn; her name was Tamar.

7 But Er, Judah’s firstborn, was evil in the sight of the LORD, and the LORD killed him [in judgment].
