The midwife - bound upon his hand a scarlet thread - The binding of the scarlet thread about the wrist of the child whose arm appeared first in the birth, serves to show us how solicitously the privileges of the birthright were preserved. Had not this caution been taken by the midwife, Pharez would have had the right of primogeniture to the prejudice of his elder brother Zarah. And yet Pharez is usually reckoned in the genealogical tables before Zarah; and from him, not Zarah, does the line of our Lord proceed. See Matthew 1:3. Probably the two brothers, as being twins, were conjoined in the privileges belonging to the birthright.

And it came to pass when she travailed,.... Her birth throes came strong and quick upon her:

that the one put out his hand; which showed that she was like to have a difficult and dangerous time of it; that the birth was not like to be according to the usual and natural order, which may be considered as a correction for her sin:

and the midwife took and bound upon his hand a scarlet thread, saying,

this came out first; she tied this to his wrist, that she might know whose hand it was, and so which was the firstborn; which, to know was a matter of consequence, since to the firstborn there were some special and peculiar privileges.

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.

38:28 It should seem the birth was hard to the mother, by which she was corrected for her sin: the children also, like Jacob and Esau, struggled for the birth - right, and Pharez who got it, is ever named first, and from him Christ descended. He had his name from his breaking forth before his brother; this breach be upon thee - The Jews, as Zarah, bid fair for the birth - right, and were marked with a scarlet thread, as those that come out first; but the Gentiles, like Pharez, or a son of violence got the start of them, by that violence which the kingdom of heaven suffers, and attained to the righteousness which the Jews came short of: yet when the fulness of time is come, all Israel shall be saved. Both these sons are named in the genealogy of our Saviour, Mt 1:3, to perpetuate the story, as an instance of the humiliation of our Lord Jesus.

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.
