Genesis 38:13-14

13Someone told Tamar, ‘Your husband's father is going to Timnah to get the wool from his sheep.’

14Tamar knew that Judah's son Shelah had now become a man. But Judah had not yet let Shelah marry her. So Tamar took off her widow's clothes and she put on other clothes. She covered her head with a veil. She did not want anyone to recognize her. Then she sat at the gate of Enaim. Enaim is a town on the road that goes to Timnah.
