Genesis 38:12-14

12And as the days were multiplied, Judah's wife, the daughter of Shua, died. And Judah was comforted, and he went up to his sheep-shearers, to Timnah, he and his friend Hirah the Adullamite.

13And it was told Tamar, saying, Behold thy father-in-law is going up to Timnah to shear his sheep.

14And she put the garments of her widowhood off from her, and covered herself with a veil, and wrapped herself, and sat in the entry of Enaim, which is on the way to Timnah; for she saw that Shelah was grown, and she was not given to him as wife.
