And he said, I will send thee a kid from the flock. And she said, Wilt thou give me a pledge, till thou send it?

Wesley's Notes

38:17 A kid from the flock - A goodly price at which her chastity and honour were valued! Had the consideration been thousands of rams, and ten thousand rivers of oil, it had not been a valuable consideration. The favour of God, the purity of the soul, the peace of the conscience, and the hope of heaven: are too precious to be exposed to sale at any such rates. He lost his Jewels by the bargain: He sent the kid according to his promise, to redeem his pawn, but the supposed harlot could not be found. He sent it by his friend, (who was indeed his back - friend, because he was aiding and abetting in his evil deeds) the Adullamite; who came back without the pledge. 'Tis a good account, if it be but true, of any place that which they here gave, that there is no harlot in this place, for such sinners are the scandals and plagues of any place. Judah sits down content to lose his signet and his bracelets, and forbids his friend to make any farther enquiry.

King James Translators' Notes

a kid: Heb. a kid of the goats

Matthew Henry's Concise Commentary

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.
