2:3 The sons of {a} Judah; Er, and Onan, and Shelah: [which] three were born unto him of the daughter of Shua the Canaanitess. And Er, the firstborn of Judah, was evil in the sight of the LORD; and he slew him.
(a) Though Judah was not Jacob's eldest son, yet he first begins with him, because he would come to the genealogy of David, of whom came Christ.
2:3 Judah - Whom he puts first, because the best part of the right of the firstborn, namely, the dominion, was conferred upon him, Gen 49:8, and because the Messiah was to come out of his loins.
2:1-55 Genealogies. - We are now come to the register of the children of Israel, that distinguished people, who were to dwell alone, and not be reckoned among the nations. But now, in Christ, all are welcome to his salvation who come to him; all have equal privileges according to their faith in him, their love and devotedness to him. All that is truly valuable consists in the favour, peace, and image of God, and a life spent to his glory, in promoting the welfare of our fellow-creatures.
