So Sarah laughed to herself, thinking, "After I am worn out will I have pleasure, especially when my husband is old too?"

So she removed her widow's clothes and covered herself with a veil. She wrapped herself and sat at the entrance to Enaim which is on the way to Timnah. (She did this because she saw that she had not been given to Shelah as a wife, even though he had now grown up.)

Judah said, "Let her keep the things for herself. Otherwise we will appear to be dishonest. I did indeed send this young goat, but you couldn't find her."
