Genesis 38:24-29

24And it came to pass about three months after, that it was told Judah, saying, Tamar thy daughter-in-law has committed fornication, and behold, she is also with child by fornication. And Judah said, Bring her forth, that she may be burned.

25When she was brought forth, she sent to her father-in-law, saying, By the man to whom these [belong] am I with child; and she said, Acknowledge, I pray thee, whose are this signet, and this lace, and this staff.

26And Judah acknowledged [them], and said, She is more righteous than I, because I have not given her to Shelah my son. And he knew her again no more.

27And it came to pass at the time of her delivery, that behold, twins were in her womb.

28And it came to pass when she brought forth, that one stretched out [his] hand, and the midwife took it and bound round his hand a scarlet thread, saying, This came out first.

29And it came to pass as he drew back his hand, that behold, his brother came out; and she said, How hast thou broken forth! on thee be the breach! And they called his name Pherez.
