One quick verse from this chapter:
Isaiah 59:17 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.
Isaiah 59:17 Gill
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, Rev 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, Rev 19:12. The apostle has borrowed these phrases from hence, and applied them to the Christian armour, Eph 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, Rev 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, Rev 19:12.

Eph 6:17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
Eph 6:18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
Eph 6:19 And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel,
