Genesis 38:12-15

After a long time Judah’s wife, the daughter of Shua, died. After Judah had gotten over his sorrow, he went to Timnah to his men who were cutting the wool from his sheep. His friend Hirah from Adullam went with him. Tamar learned that Judah, her father-in-law, was going to Timnah to cut the wool from his sheep. So she took off the clothes that showed she was a widow and covered her face with a veil to hide who she was. Then she sat down by the gate of Enaim on the road to Timnah. She did this because Judah’s younger son Shelah had grown up, but Judah had not made plans for her to marry him. When Judah saw her, he thought she was a prostitute, because she had covered her face with a veil.
