Genesis 38:5; Genesis 38:11; Genesis 38:14; Genesis 38:26

5 She gave birth to still another son and named him Shelah. It was at Kezib that she gave birth to him.

11 Judah then said to his daughter-in-law Tamar, “Live as a widow in your father’s household until my son Shelah grows up.” For he thought, “He may die too, just like his brothers.” So Tamar went to live in her father’s household.

14 she took off her widow’s clothes, covered herself with a veil to disguise herself, and then sat down at the entrance to Enaim, which is on the road to Timnah. For she saw that, though Shelah had now grown up, she had not been given to him as his wife.

26 Judah recognized them and said, “She is more righteous than I, since I wouldn’t give her to my son Shelah.” And he did not sleep with her again.
