For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloke.

He put on justice as a breastplate, and a helmet of salvation upon his head: he put on the garments of vengeance, and was clad with zeal as with a cloak.

And he put on righteousness as a breastplate, and a helmet of salvation upon his head; and he put on garments of vengeance for clothing, and was clad with zeal as a cloak.

For he put on righteousness as a breast-plate, and a helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloke.

And He putteth on righteousness as a breastplate, And an helmet of salvation on His head, And He putteth on garments of vengeance for clothing, And is covered, as with an upper-robe, with zeal.

Yes, he put on righteousness as a breastplate, and salvation as a head-dress; and he put on punishment as clothing, and wrath as a robe.

And He put on righteousness as a coat of mail, And a helmet of salvation upon His head, And He put on garments of vengeance for clothing, And was clad with zeal as a cloak.

He clothed himself with justice as with a breastplate, and with a helmet of salvation upon his head. He put on the vestments of vengeance, and he was covered with zeal as with a cloak.

Et induit justitiam, sicut loricam; et galeam salutis capiti suo. Induit, inquam, ultionem quasi vestem, et indignatione amictus fuit vice pallii.

And he put on righteousness as a coat of mail. Here he equips God with his armor, for the purpose both of confirming more and more the confidence of believers, and of stripping all men of all confidence in their own strength. The meaning of the verse amounts to this, that God is in want of nothing for discomfiting his enemies and gaining the victory; because from his righteousness, power, and grace, and from his ardent love of his people, he will make for himself panoplian complete armor. And this is again worthy of remark; for, although we acknowledge that God is sufficiently powerful, yet we are not satisfied with it, but at. the same time seek other help. Thus our minds are always inclined to unbelief, so that they fasten on inferior means, and are greatly entangled by them. In order to correct this vice, Isaiah presents this lively description; as if he had said, "Know ye that God has in his hand all the safeguards of your salvation, and will be in want of nothing to deliver you in spite of enemies and bring you back to your native country; and therefore there is no reason why you should tremble." Besides, there is nothing to which we are more prone than to imagine that we bestow something on God, and thus to claim for ourselves some part of the praise which ought to remain undivided with him. When he clothes God with vengeance, and with indignation as a cloak, this relates to enemies, against whom God is said to be enraged for the sake of his people; and thus, the more that Satan labors and makes every effort against us, so much the more does God kindle with zeal, and so much the more powerfully does he rise up, to render assistance to us. Although, therefore, Satan and all the reprobate do not rest, but raise up obstacles of every kind to prevent our salvation, and even exert themselves furiously to destroy us, yet, by his power alone, God will defeat all their efforts.

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. Instead of being an earthly conqueror, clad in steel, and defended with brass, his weapons were moral weapons, and his conquests were spiritual. The various parts of his weapons were 'righteousness.' 'salvation,' and 'zeal.' This statement should have been, in itself, sufficient to keep the Jews front anticipating a Messiah who would be a bloody warrior and distinguished for deeds of conquest and blood. This figure of speech is not uncommon. Paul (in Ephesians 6:14-17; compare 2-Corinthians 6:7) has carried it out to greater length, and introduced more particulars in the description of the spiritual armor of the Christian.
And an helmet of salvation - The helmet was a piece of defensive armor for the head. It was made of iron or brass, and usually surmounted by a crest of hair. It was designed to guard the head from the stroke of a sword. No particular stress should be laid on the fact, that it is said that 'salvation' would be the helmet. The design is to represent the Redeemer by the figure of a hero clad in armor, yet there seems to be no particular reason why salvation should be referred to as the helmet, or righteousness as the cuirass or breastplate. Nothing is gained by a fanciful attempt to spiritualize or explain them.
And he put on the garments of vengeance for clothing - By 'garments,' here, Vitringa supposes that there is reference to the interior garments which were worn by the Orientals corresponding to the tunic of the Romans. But it is more probable that the allusion is to the other parts of the dress or armor in general of the ancient warrior. The statement that he was clad in the garments of vengeance means, that he would go forth to vindicate his people, and to take vengeance on his foes. It would not be for mere defense that he would be thus armed for battle; but he would go forth for aggressive movements, in subduing his enemies and delivering his people (compare Isaiah 63:1-6).
And was clad with zeal as a cloak - The cloak worn by men in military as well as in civil life, was a loose flowing robe or mantle that was thrown over the body, usually fastened on the right shoulder by a hook or clasp, and suffered to flow in graceful folds down to the feet. In battle, it would be laid aside, or secured by a girdle about the loins. Vitringa remarks, that, as it was usually of purple color, it was adapted to represent the zeal which would burn for vengeance on an enemy. But the whole figure here is that drawn from a warrior or a conqueror: a hero prepared alike for defense and offence. The idea is, that he would be able to defend and vindicate his people, and to carry on aggressive warfare against his enemies. But it was not to be a warfare literally of blood and carnage. It was to be such as would be accomplished by righteousness, and zeal, and a desire to secure salvation. The triumph of righteousness was the great object still; the conquests of the Redeemer were to be those of truth.

For clothing "For his clothing" - תלבשת tilbosheth. "I cannot but think that this word, תלבשת tilbosheth, is an interpolation.
1. It is in no one ancient version.
2. It is redundant in the sense, as it is before expressed in בגדי bigdey.
3. It makes the hemistich just so much longer than it ought to be, if it is compared with the others adjoining.
4. It makes a form of construction in this clause less elegant than that in the others.
5. It might probably be in some margin a various reading for בגדי bigdey, and thence taken into the text.
This is more probable, as its form is such as it would be if it were in regimine, as it must be before נקם nakam." - Dr. Jubb. Two sorts of armor are mentioned: a breast-plate and a helmet, to bring righteousness and salvation to those who fear him; and the garments of vengeance and the cloak of zeal for the destruction of all those who finally oppose him, and reject his Gospel.

For he put on righteousness as a breastplate, and an (q) helmet of salvation upon his head; and he put on the garments of vengeance [for] clothing, and was clad with zeal as a cloke.
(q) Signifying that God has all means at hand to deliver his Church and to punish their enemies.

For he put on righteousness as a breastplate,.... 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, Revelation 19:11, 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 helmet of salvation upon his head; the salvation he will work out for his people will be very conspicuous; it will be seen by all, as the helmet on the head; and he will have the glory of it, on whose head are many crowns, Revelation 19:12. The apostle has borrowed these phrases from hence, and applied them to the Christian armour, Ephesians 6:14,
and he put on the garments of vengeance for clothing; or, "he clothed himself with vengeance as a garment" (k); he wrapped himself in it, and resolved to execute it on his and his people's enemies; the time being come to avenge the blood of his servants, by shedding the blood of their adversaries, with which his garments will be stained; and therefore is represented as having on a vesture dipped in blood, Revelation 19:13,
and was clad with zeal as a cloak; with zeal for his own glory, and the interest of his people, and against antichrist, and all antichristian worship and doctrine; and therefore his eyes are said to be as a flame of fire, Revelation 19:12.
(k) "et ultionem induit tanquam vestem", Tigurine version.

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, Romans 12:19), or "cloak of zeal" (in the sense of judicial fury punishing the wicked; this zeal belongs properly to God, 2-Kings 10:16; Romans 10:2; Philippians 3:6; "zeal," in the sense of anxiety for the Lord's honor, they have, Numbers 25:11, Numbers 25:13; Psalm 69:9; 2-Corinthians 7:11; 2-Corinthians 9:2); and for "salvation," which is of God alone (Psalm 3:8), they have as their helmet, "the hope of salvation" (1-Thessalonians 5:8). The "helmet of salvation" is attributed to them (Ephesians 6:14, Ephesians 6:17) in a secondary sense; namely, derived from Him, and as yet only in hope, not fruition (Romans 8:24). The second coming here, as often, is included in this representation of Messiah. His "zeal" (John 2:15-17) at His first coming was but a type of His zeal and vengeance against the foes of God at His second coming (2-Thessalonians 1:8-10; Revelation 19:11-21).

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.
