23:1-8 Woe be to those who are set to feed God's people, but take no concern to do them good! Here is a word of comfort to the neglected sheep. Though only a remnant of God's flock is left, he will find them out, and they shall be brought to their former habitations. Christ is spoken of as a branch from David's family. He is righteous himself, and through him all his people are made righteous. Christ shall break the usurped power of Satan. All the spiritual seed of believing Abraham and praying Jacob shall be protected, and shall be saved from the guilt and dominion of sin. In the days of Christ's government in the soul, the soul dwells at ease. He is here spoken of as the Lord our Righteousness. He is so our Righteousness as no creature could be. His obedience unto death is the justifying righteousness of believers, and their title to heavenly happiness. And their sanctification, as the source of all their personal obedience is the effect of their union with him, and of the supply of this Spirit. By this name every true believer shall call him, and call upon him. We have nothing to plead but this, Christ has died, yea, rather is risen again; and we have taken him for our Lord. This righteousness which he has wrought out to the satisfaction of law and justice, becomes ours; being a free gift given to us, through the Spirit of God, who puts it upon us, clothes us with it, enables us to lay hold upon it, and claim an interest in it. The Lord our Righteousness is a sweet name to a convinced sinner; to one that has felt the guilt of sin in his conscience; seen his need of that righteousness, and the worth of it. This great salvation is far more glorious than all former deliverances of his church. May our souls be gathered to Him, and be found in him.
6. Judah … Israel … dwell safely—Compare Jer 33:16, where "Jerusalem" is substituted for "Israel" here. Only Judah, and that only in part, has as yet returned. So far are the Jews from having enjoyed, as yet, the temporal blessings here foretold as the result of Messiah's reign, that their lot has been, for eighteen centuries, worse than ever before. The accomplishment must, therefore, be still future, when both Judah and Israel in their own land shall dwell safely under a Christocracy, far more privileged than even the old theocracy (Jer 32:37; De 33:28; Isa 54:1-17; 60:1-22; 65:17-25; Zec 14:11).
shall be called, the Lord—that is, shall be (Isa 9:6) "Jehovah," God's incommunicable name. Though when applied to created things, it expresses only some peculiar connection they have with Jehovah (Ge 22:14; Ex 17:15), yet when applied to Messiah it must express His Godhead manifested in justifying power towards us (1Ti 3:16).
our—marks His manhood, which is also implied in His being a Branch raised unto David, whence His human title, "Son of David" (compare Mt 22:42-45).
Righteousness—marks His Godhead, for God alone can justify the ungodly (compare Ro 4:5; Isa 45:17, 24, 25).
