Isaiah 59:17

“For he put on righteousness as a breastplate, &c.] Here the Lord is represented as a warrior clothed with armour, and as Christ is, and as he will appear in the latter day on the behalf of his people, and against their enemies, who is called faithful and true, and in righteousness will make war, (<661911>Revelation 19:11-13), he will proceed according to justice and equity in righting the wrongs and avenging the injuries of his people; and both in saving them, and destroying their enemies, he will secure the honour of his faithfulness and justice, and the credit of his name and character; which will be preserved by his conduct, as the breast and inward parts are by the breastplate: and an…”

“Messiah is represented as a warrior armed at all points, going forth to vindicate His people. Owing to the unity of Christ and His people, their armor is like His, except that they have no "garments of vengeance" (which is God's prerogative, Rom 12:19), or "cloak of zeal" (in the sense of judicial fury punishing the wicked; this zeal belongs properly to God, Kg2 10:16; Rom 10:2; Phi 3:6; "zeal," in the sense of anxiety for the Lord's honor, they have, Num 25:11, Num 25:13; Psa 69:9; Co2 7:11; Co2 9:2); and for "salvation," which is of God alone (Psa 3:8), they have as their helmet, "the hope of salvation" (Th1 5:8). The "helmet of salvation" is attributed to them (Eph 6:14, Eph 6:17) in a…”

“For he put on righteousness - That is, God the Redeemer. The prophet here introduces him as going forth to vindicate his people clad like an ancient warrior. In the declaration that he ‘put on righteousness,’ the essential idea is, that he was pure and holy. The same image is used by the prophet in another figure in Isaiah 11:5 (see the note at that place). As a breastplate - The breastplate was a well-known piece of ancient armor, designed to defend the breast from the darts and the sword of an enemy. The design here is, to represent the Redeemer as a hero; and accordingly allusion is made to the various parts of the armor of a warrior. Yet he was not to be literally armed for battle.…”

“For - God, resolving to appear as a man of war, puts on his arms; he calls righteousness his breast - plate, to shew the justness of his cause, as also his faithfulness in making good his promises. Vengeance - Or garments made of vengeance: as God is said to put on the former for their sakes, whom he would preserve, so he puts on these for their sakes, whom he will destroy, namely, his peoples enemies. Zeal - For his own honour, and for his own people. The sum of all these expressions is, to describe both the cause and effect together; the cause was righteousness and zeal in God, the effect, salvation to his people, and vengeance on his enemies. Isaiah 59:18”

“he put on righteousness: Isa 11:5, Isa 51:9; Job 29:14; Rom 13:12-14; Co2 6:7; Eph 6:14, Eph 6:17; Th1 5:8; Rev 19:11 the garments: Deu 32:35-43; Psa 94:1; Th2 1:8; Heb 10:30 with zeal: Isa 9:7, Isa 63:15; Psa 69:9; Zac 1:14; Joh 2:17 Isaiah 59:18”
