Genesis 38
14 Ref She took off of her the garments of her widowhood, and covered herself with her veil, and wrapped herself, and sat in the gate of Enaim, which is by the way to Timnah; for she saw that Shelah was grown up, and she wasn't given to him as a wife.
15 When Judah saw her, he thought that she was a prostitute, for she had covered her face.
