And it came to pass in the time of her travail,.... When her time to bring forth was come, and her pains were on her, and her midwife with her:

that, behold, twins were in her womb; which the midwife could discover before the birth of either.

Thamar brought forth twins; and a circumstance occurred at the birth, which does occasionally happen when the children lie in an abnormal position, and always impedes the delivery, and which was regarded in this instance as so significant that the names of the children were founded upon the fact. At the birth ויּתּן־יד "there was a hand," i.e., a hand came out (יתּן as in Job 37:10; Proverbs 13:10), round which the midwife tied a scarlet thread, to mark this as the first-born.

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

38:1-30 The profligate conduct of Judah and his family. - This chapter gives an account of Judah and his family, and such an account it is, that it seems a wonder that of all Jacob's sons, our Lord should spring out of Judah, Heb 7:14. But God will show that his choice is of grace and not of merit, and that Christ came into the world to save sinners, even the chief. Also, that the worthiness of Christ is of himself, and not from his ancestors. How little reason had the Jews, who were so called from this Judah, to boast as they did, Joh 8:41. What awful examples the Lord proclaims in his punishments, of his utter displeasure at sin! Let us seek grace from God to avoid every appearance of sin. And let that state of humbleness to which Jesus submitted, when he came to put away sin by the sacrifice of himself, in appointing such characters as those here recorded, to be his ancestors, endear the Redeemer to our hearts.
