Genesis 38:27

27 When the time came for her to give birth, it was discovered that she was going to have twins.

Genesis 38:27 In-Context

25 As she was being taken out, she sent word to her father-in-law: "I am pregnant by the man who owns these things. Look at them and see whose they are - this seal with its cord and this walking stick."
26 Judah recognized them and said, "She is in the right. I have failed in my obligation to her - I should have given her to my son Shelah in marriage." And Judah never had intercourse with her again.
27 When the time came for her to give birth, it was discovered that she was going to have twins.
28 While she was in labor, one of them put out an arm; the midwife caught it, tied a red thread around it, and said, "This one was born first."
29 But he pulled his arm back, and his brother was born first. Then the midwife said, "So this is how you break your way out!" So he was named Perez.
