Genesis 38:21-25

He asked the people of her place, saying, “Where is the temple prostitute who was by the road at Enaim?” But they said, “There has been no temple prostitute here.”

So he returned to Judah, and said, “I did not find her; and furthermore, the people of the place said, ‘There has been no temple prostitute here.’ ”

Then Judah said, “Let her keep them, otherwise we will become a laughingstock. After all, I sent this young goat, but you did not find her.”

Now it was about three months later that Judah was informed, “Your daughter-in-law Tamar has prostituted herself, and behold, she is also pregnant by prostitution.” Then Judah said, “Bring her out and have her burned!”

It was while she was being brought out that she sent word to her father-in-law, saying, “I am pregnant by the man to whom these things belong.” She also said, “Please examine and see, whose signet ring and cords and staff are these?”
