Genesis 38:24-26

About three months later Judah was told, “Tamar your daughter-in-law has been immoral. Moreover, she is pregnant by immorality.” And Judah said, “Bring her out, and let her be burned.” As she was being brought out, she sent word to her father-in-law, “By the man to whom these belong, I am pregnant.” And she said, “Please identify whose these are, the signet and the cord and the staff.” Then Judah identified them and said, “She is more righteous than I, since I did not give her to my son Shelah.” And he did not know her again.
