Genesis 38:12-14

12Now the days became many, and Shua’s daughter, Judah’s wife, died. After Judah consoled himself, he went up to Timnah to his sheepshearers, he and his friend Hirah the Adullamite.

13Then Tamar was told, “Look! Your father-in-law is going up to Timnah to shear his flocks.”

14And she removed her widow’s clothes from herself, covered herself with a veil, wrapped herself, and sat by the entrance to the springs on the way to Timnah (for she saw that Shelah had grown up and she had not been given to him as a wife).
