Genesis 38:17-18

17And he said, I will send [thee] a kid of the goats from the flock. And she said, Wilt thou give [me] a pledge, until thou send it?

18And he said, What pledge shall I give thee? And she said, Thy signet, and thy lace, and thy staff which is in thy hand. And he gave [it] her, and went in to her; and she conceived by him.
