“There was only one remedy in the secret of the divine plan that could help the fallen living in the general ruin of the entire human race. This remedy was that one of the sons of Adam should be born free and innocent of original transgression, to prevail for the rest by his example and by his merits. This was not permitted by natural generation. There could be no clean offspring from our faulty stock by this seed. The Scripture says, "Who can make a clean thing conceived of an unclean seed? Isn't it you alone?" David's Lord was made David's Son, and from the fruit of the promised branch sprang. He is one without fault, the twofold nature coming together into one person. By this one and the same conception and birth sprung our Lord Jesus Christ, in whom was present both true Godhead for the performance of mighty works and true manhood for the endurance of sufferings.”

“Here he threatens punishment: and first the threat is set forth against the shepherds. "I will visit." Above, 21: "I will visit upon you according to the fruit of your studies." Second, the consolation of the scattered flock is set forth, "I will gather": where first he sets forth the gathering. Ezekiel 34: "I will lead them out from the peoples, and gather them from the lands," etc. And the prosperity of their state, "and they shall increase." Genesis 1: "Increase, and multiply, and fill the earth." Second, he promises them the amendment of their prelates: and first he promises them careful princes, setting forth the carefulness of the shepherds: "and I will raise up" — when you shall already have fallen away into nothing — "shepherds." Ezra, and others, according to some. But better, the apostles. Above, 3: "I will give you shepherds according to my heart, and they shall feed you with knowledge and doctrine." And the usefulness of their carefulness, namely security: "they shall not fear" — as to the outward signs of fear — and "they shall not dread" — inwardly — "and none shall be missing out of their number," as if to say: none of the number of the Church shall fear, or fail through the negligence of the apostles. Or it is referred to the number of the predestined. John 17: "none of them has perished but the son of perdition." This security, however, is not perfected in this life, but will be perfected when perfect charity casts out fear: 1 John 4 — but it will be consummated in the future. Second, he promises them a best king, showing the fitness of the time: "behold" — on account of certainty — "the days" — of grace. 2 Corinthians 6: "behold, now is the acceptable time, behold, now is the day of salvation." The condition of the coming king as to the nobility of his lineage: "and I will raise up to David a just branch." Below, 33: "I will make to spring up to David a branch of justice, and he shall do judgment and justice in the earth." As to the authority of his dignity: "and the king shall reign" — not only over the Jews, but also over all kings. Luke 1: "and he shall reign in the house of Jacob forever." Daniel 7: "whose kingdom is an everlasting kingdom, and all kings shall serve him, and obey." As to the wisdom of his heart: "and he shall be wise" — nay rather, wisdom itself. Corinthians 1: "Christ the power of God, and the wisdom of God." And as to the execution of justice: "and he shall do judgment" — in the first coming, against the Devil, who was called the prince of the world: John 12: "now is the judgment of the world, now shall the prince of this world be cast out," namely, into the outer darkness; but in the second, against all, punishing by a general sentence. John 5: "the father judges no one, but has given all judgment to the son." And "justice," which he taught was to be kept. Matthew 5: "unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven." And for fulfilling it, the help of grace: whence he sets forth the usefulness of his coming, as to salvation from punishment: "in those days it shall be saved": in the first coming, in part; in the second coming, universally, when all Israel shall be saved: Romans 11. Isaiah 10: "if the number of the children of Israel be as the sand of the sea, the remnant shall be converted of it." And as to security: "and Israel shall dwell confidently." And this is to be expounded as above. Isaiah 32: "my people shall sit in the beauty of peace, in the tabernacles of justice, and in wealthy rest." He says "Judah" as to the two tribes; "Israel" as to the ten, to signify that in the faith of Christ they shall be in concord. Hosea 1: "and they shall appoint themselves one head," etc.”

“In his days Judah shall be saved,.... In the days of the Messiah, the righteous Branch, and reigning prosperous King, not only the people of the Jews, God's elect among them, but all that truly embrace him, and confess him, as Judah's name signifies, shall be saved from all their sins; from the law, its curse and condemnation; and from wrath to come; and from all their spiritual enemies. In the latter part of his days all Israel shall be saved, Rom 11:26; and Israel shall dwell safely; without any fear of enemies, being saved from them; being in that city, the church, which has salvation for walls and bulwarks; angels encamping about them; the Lord as a wall of fire around them; the Spirit lifting up a standard against their enemies, when they come in like a flood; and the Messiah their rock and refuge, and strong tower, their strength and righteousness; as follows: for all the salvation and safety of the Lord's people are owing to the righteousness of Christ; the effect of which is peace, quietness, and assurance for ever: and this is his name whereby he shall be called, THE LORD OUR RIGHTEOUSNESS; because he is the author of righteousness to his people, and is only so; no creature could be the author of it; unrighteous man cannot be the author of righteousness; and the righteousness of an angel is of no advantage to man; and indeed neither of the other divine Persons is the Lord our righteousness; for though they are both Jehovah, the Father and the Spirit, yet not our righteousness: the Father appointed and sent Christ to work it out; he approved and accepted of it, when wrought out; and imputes it to his people; but is not the author of it: so the Spirit convinces of the need of it; reveals it, and brings it near; works faith to receive it; and applies it, and pronounces a person justified by it; but is not the author of it; that the Son of God only is; who is become so by his obedience to the law, and by bearing the penalty of it; and who, having been delivered for our offences, rose again for our justification: and this righteousness, which he has wrought out to the satisfaction of law and justice, becomes "ours"; it being signed for us, and wrought out for us, by a free gift of it is given to us; ours through the imputation of it to us by the Father, and in virtue of our union to Christ, and interest in him; and through the application of it to us by the Spirit of God; who puts it upon us, and clothes us with it, and enables us to lay hold upon it, and claim interest in it; and which may be meant by Christ being "called our righteousness"; for the meaning is, not that he should commonly go by this name; but only that he should be that unto us which it signifies; and that we should by faith, even every true Israelite, every believer, call him our righteousness; say that we have righteousness in him make mention of that continually, and express our desires to be found atone in it; for so the words may be rendered, "and this is the name whereby he shall call him (g), THE LORD OUR RIGHTEOUSNESS"; and a sweet name to a sensible sinner it is; to one that has felt the guilt of sin in his conscience; seen his need of a righteousness, and the worth of it. That the Messiah is here meant is acknowledged by the Jews, ancient and modern (h). (g) "hoc nomen ejus est quo vocabit eum Israel", Junius & Tremellius; "quo vocabit eum unusquique", Piscator.

“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; Deu 33:28; Isa. 54:1-17; 60:1-22; Isa 65:17-25; Zac 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 (Gen 22:14; Exo 17:15), yet when applied to Messiah it must express His Godhead manifested in justifying power towards us (Ti1 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 Mat 22:42-45). Righteousness--marks His Godhead, for God alone can justify the ungodly (compare Rom 4:5; Isa 45:17, Isa 45:24-25).”

“Jer 23:6 exhibits the welfare which the "branch" will, by His wise and just rule, secure for the people. Judah shall be blessed with welfare (נושׁע), and Israel dwell safely; that blessing will come into fulfilment which Moses set before the people's view in Deu 33:28. יהוּדה as the totality of the inhabitants is construed as feminine, as in Jer 3:7; Jer 14:2, etc. Israel denotes the ten tribes. Under the just sceptre of the Messiah, all Israel will reach the destiny designed for it by the Lord, will, as God's people, attain to full dignity and glory. This is the name by which they shall call Him, the branch of David: Jahveh our Righteousness. The suffix in יקראו refers to "righteous branch." Instead of the 3 pers. sing. יקרא with the suffix ו, some codd. have the plur. יקראוּ. This some polemical authors, such as Raim., Martini, Galatin, hold to be the true reading; and they affirmed the other had proceeded from the Jews, with the design of explaining away the deity of the Messiah. The Jews translated, they said: This is the name whereby Jahveh will call him: Our Righteousness; which is indeed the rendering of R. Saad. Gaon apud Aben Ezra, and of Menasse ben Israel. But this rendering is rejected by most Jewish comm. as being at variance with the accents, so that the impugned reading could not well have been invented by the Jews for polemical purposes. יקראו is attested by most codd., and is rendered by the lxx, so that the sense can be none other than: they will call the righteous branch of David "Jahveh our Righteousness." Most comm., including even Hitz., admit that the suffix refers to צמח, the principal person in both verses. Only Ew., Graf, and Ng. seek to refer it to Israel, because in Jer 33:16 the same name is given to Jerusalem. But the passage cited does not prove the case. To call any one by a name universally denotes in the prophetic usage: to set him forth as that which the name expresses; so here: the branch of David will manifest Himself to the people of Israel as Jahve Tsidkenu. This name is variously expounded. The older Christian comm. understand that the Messiah is here called Jehovah, and must therefore be true God, and that He is called our righteousness, inasmuch as He justifies us by His merit. (Note: Thus the Vulg. renders: Dominus justus noster; and even Calv. says: Quicunque sine contentione et amarulentia judicant, facile vident, idem nomen competer in Christum, quatenus est Deus, sicuti nomen filii Davidis respectu humanae naturae ei tribuitur. - Omnibus aequis et moderatis hoc constabit, Christum hic insigniri duplici elogio, ut in eo nobis commendet propheta tam deitatis gloriam, quam veritatem humanae naturae; and by the righteousness he understands justification by the merits of Christ.) But the rabbinical interpreters, headed by the Chald., take the name to be an abbreviation of a sentence; so e.g., Kimchi: Israel vocabit Messiam hoc nomine, quia ejus temporibus Domini justitia nobis firma, jugis et non recedet. They appeal to Jer 33:17 and to other passages, such as Exo 17:15, where Moses calls the altar "Jahveh my Banner," and Gen 33:20, where Jacob gives to the altar built by him the name El elohe Jisrael. Hgstb. has rightly pronounced for this interpretation. The passages cited show who in such names an entire sentence is conveyed. "Jahveh my Banner" is as much as to say: This altar is dedicated to Jahveh my banner, or to the Almighty, the God of Israel. So all names compounded of Jahveh; e.g., Jehoshua = Jahveh salvation, brief for: he to whom Jahveh vouchsafes salvation. So Tsidkijahu = Jahve's righteousness, for: he to whom Jahveh deals righteousness. To this corresponds Jahveh Tsidkenu: he by whom Jahveh deals righteousness. We are bound to take the name thus by the parallel passage, Jer 33:16, where the same name is given to Jerusalem, to convey the thought, that by the Messiah the Lord will make Jerusalem the city of Righteousness, will give His righteousness to it, will adorn and glorify it therewith. צדקנוּ is not to be referred, as it is by the ancient Church comm., to justification through the forgiveness of sins. With this we have not here to do, but with personal righteousness, which consists in deliverance from all unrighteousness, and which is bound up with blessedness. Actual righteousness has indeed the forgiveness of sins for its foundation, and in this respect justification is not to be wholly excluded; but this latter is here subordinate to actual righteousness, which the Messiah secures for Israel by the righteousness of His reign. The unrighteousness of the former kings has brought Israel and Judah to corruption and ruin; the righteousness of the branch to be hereafter raised up to David will remove all the ruin and mischief from Judah, and procure for them the righteousness and blessedness which is of God. - "What Jeremiah," as is well remarked by Hgstb., "sums up in the name Jehovah Tsidkenu, Ezekiel expands at length in the parallel Eze 34:25-31 : the Lord concludes with them a covenant of peace; rich blessings fall to their lot; He breaks their yoke, frees them from bondage; they do not become the heathen's prey." These divine blessings are also to be conferred upon the people by means of the righteous branch. What the ancient Church comm. found in the name was true as to the substance. For as no man is perfectly righteous, so no mere earthly king can impart to the people the righteousness of Jahveh in the full sense of the term; only He who is endowed with the righteousness of God. In so far the Godhead of this King is contained implicite in the name; only we must not understand that he that bore the name is called Jahveh. But that righteousness, as the sum of all blessing, is set before the people's view, we may gather from the context, especially from Jer 23:7 and Jer 23:8, where it is said that the blessings to be conferred will outshine all former manifestations of God's grace. This is the sense of both verses, which, save in the matter of a trifling change in Jer 23:8, are verbally repeated from Jer 16:14 and Jer 16:15, where they have already been expounded. (Note: The lxx have omitted both these verses here, and have placed them at the end of the chapter, after Jer 23:40; but by their contents they do not at all belong to that, whereas after Jer 23:6 they are very much in place, as even Hitz. admits. In the text of the lxx handed down, Jer 23:6 ends with the words: ̓Ιωσεδὲκ ἐν τοῖς προφήταις; and ̓Ιωσεδὲκ may be said to correspond to יהוה צדקנוּ, and ἐν τοῖς προφήταις to לנּביאים, Jer 23:9. Hitz. and Gr. therefore infer that Jer 23:7 and Jer 23:8 were wanting also in the Heb. text used by the translator, and that they must have been added by way of supplement, most probably from another MS. This inference is thought to find support in the assumption that, because the Greek MSS have no point between ̓Ιωσεδὲκ and ἐν τοῦς προφήταις, therefore the Alexandrian translator must have joined these words together so as to make one - meaningless - sentence. A thoroughly uncritical conclusion, which could be defended only if the Alex. translators had punctuated their Greek text as we have it punctuated in our printed editions. And if a later reader of the lxx had added the verses from the Hebrew text, then he would certainly have intercalated them at the spot where they stood in the original, i.e., between Jer 23:6 and Jer 23:9. Their displacement to a position after Jer 23:40 is to be explained from the fact that in Jer 16:14 and Jer 16:15 they immediately follow a threatening: and is manifestly the work of the translator himself, who omitted them after Jer 23:6, understanding them as of threatening import, because a threatening seemed to him to be out of place after Jer 23:6.)”
