Genesis 38:11; Genesis 38:14; Genesis 38:29; Genesis 38:30

11 Then Judah said to Tamar his daughter-in-law, "Remain a widow in your father's house, till Shelah my son grows up"--for he feared that he would die, like his brothers. So Tamar went and remained in her father's house.

14 she took off her widow's garments and covered herself with a veil, wrapping herself up, and sat at the entrance to Enaim, which is on the road to Timnah. For she saw that Shelah was grown up, and she had not been given to him in marriage.

29 But as he drew back his hand, behold, his brother came out. And she said, "What a breach you have made for yourself!" Therefore his name was called Perez.

30 Afterward his brother came out with the scarlet thread on his hand, and his name was called Zerah.
