Genesis 38:26-28

Amplified Bible

²⁶ Judah recognized the articles, and said, “She has been more righteous [in this matter] than I, because I did not give her to my son Shelah [as I had promised].” And Judah did not have [intimate] relations with her again.

²⁷ Now when the time came for her to give birth, there were twins in her womb. ²⁸ And when she was in labor, one [baby] put out his hand, and the midwife took his hand and tied a scarlet thread on it, saying, “This one was born first.”
