Genesis 38:27

24 And it came to pass about three months after, that it was told to Judah, saying, Tamar thy daughter-in-law hath played the harlot; and also, behold she [is] with child by lewdness: and Judah said, Bring her forth, and let her be burnt.

25 When she [was] brought forth, she sent to her father-in-law, saying, By the man whose these [are], am I with child: and she said, Discern, I pray thee, whose [are] these, the signet, and bracelets, and staff.

26 And Judah acknowledged [them], and said She hath been more righteous than I; because that I gave her not to Shelah my son: and he knew her again no more.

27 And it came to pass in the time of her travail, that behold, twins [were] in her womb.

28 And it came to pass when she travailed, that [the one] put out [his] hand; and the midwife took and bound upon his hand a scarlet thread, saying, This came out first.

29 And it came to pass as he drew back his hand, that behold, his brother came out; and she said, How hast thou broken forth? [this] breach [be] upon thee: therefore his name was called Pharez.

30 And afterwards came out his brother that had the scarlet thread upon his hand; and his name was called Zarah.
