38:1 And it came to pass at that time, that {a} Judah went down from his brethren, and turned in to a certain Adullamite, whose name [was] Hirah.
(a) Moses describes the genealogy of Judah, because the Messiah should come from him.
38:1 Judah went down from his brethren - Withdrew for a time from his father's family, and got intimately acquainted with one Hirah an Adullamite. When young people that have been well educated begin to change their company, they will soon change their manners, and lose their good education. They that go down from their brethren, that forsake the society of the seed of Israel, and pick up Canaanites for their companions, are going down the hill apace.
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.
