Jeremiah 23:5,6

I will raise unto David a righteous branch The house of David seemed to be quite sunk and ruined by the threatening pronounced against Jeconiah, (Jeremiah 22:30,) that none of his seed should ever sit upon the throne of David: but here we have a promise which effectually secures the honour of the covenant made with David, notwithstanding that threatening; for by it his house will be raised out of its ruins to a greater lustre than ever, and shine brighter than it did even in the days of Solomon. We have not so many prophecies of Christ in this book as we had in that of the Prophet Isaiah. But here we have a very illustrious one. Of him, doubtless, the prophet here speaks, and of no other person. Even the Jewish doctors, as well as Christian interpreters, understand this as a prophecy of the Messiah, who is called the branch: Isaiah 4:2; Isaiah 53:2; and the man the branch, Zechariah 3:8. And here he is termed the righteous branch, not only because he himself was righteous, but because he makes his people righteous; and a king that shall reign and prosper Not like kings that now were of the house of David, going backward in all their affairs, but one that shall set up a kingdom in the world, which shall be victorious over all opposition; one to whose hands the good pleasure of the Lord shall be committed, and under whose care and management it shall prosper; one who shall execute judgment and justice in the earth All the world over, Psalms 96:13. The present kings of David's line were unjust and oppressive, and their affairs therefore did not prosper; but this king shall break the usurped power of Satan, institute a perfect rule of holy living, and in due time make all the world righteous. In his days That is, under his dominion, when his kingdom shall be set up and established upon earth; Judah shall be saved, &c. The people of God, typified by Judah and Israel, shall be saved with a spiritual and eternal salvation, a salvation from the guilt and power of sin, into the favour and image of God here, and into the kingdom of his glory hereafter. At which kingdom, till they arrive, God will be a special protection to them, their refuge and strength, and very present help in trouble; so that they shall dwell safely Confiding in the care of their strong helper, and preserved in perfect peace. And this is his name whereby he shall be called Namely, by his people, and by God; the name whereby he shall be known, and which shall at once be descriptive both of his person and office. THE LORD, Hebrew, JEHOVAH OUR RIGHTEOUSNESS Though of the seed of David according to the flesh, he shall indeed be JEHOVAH, God in human nature, and OUR RIGHTEOUSNESS; namely, justifying us by his merits, sanctifying us by his Spirit, and directing us in every part of our duty by his doctrine and example; the end of the law for righteousness to every one that believeth in him with a faith that worketh by love.
