Genesis 38:24-30

24About three months later, Judah was told, “Your daughter-in-law Tamar has been a prostitute—look, she’s even pregnant by prostitution.” “Bring her out!” Judah said, “and let her be burned.”

25As she was being brought out, she sent word to her father-in-law saying, “I’m pregnant by the man to whom these things belong.” Then she said, “Do you recognize whose these are—the seal, the cords and the staff?”

26Then Judah recognized them and said, “She is more righteous than I, since I didn’t give her to my son Shelah.” He was not intimate with her again.

27Now when it was time for her to give birth, behold there were twins in her womb.

28While she was giving birth, one stuck out his hand, and the midwife took a scarlet thread and tied it to his hand saying, “This one came out first.”

29But as he was pulling his hand back in, behold, his brother came out. So she said, “How you have broken through! The breach is because of you.” And he named him Perez.

30Afterward his brother, on whose hand was the scarlet thread, came out. And he named him Zerah.
