Genesis 38:26-28

Revised Standard Version

²⁶ Then Judah acknowledged them and said, “She is more righteous than I, inasmuch as I did not give her to my son Shelah.” And he did not lie with her again.

²⁷ When the time of her delivery came, there were twins in her womb. ²⁸ And when she was in labor, one put out a hand; and the midwife took and bound on his hand a scarlet thread, saying, “This came out first.”
