Charles Ellicott Commentary Isaiah 59:17

"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 mantle." — Isaiah 59:17 (ASV)

He put on righteousness ... —The close parallelism with Isaiah 11:0 points, as far as it goes, to identity of authorship; and that with Ephesians 6:14-17 suggests a new significance for Saint Paul’s whole armour of God.

The garments of vengeance ... —As parts of a warrior’s dress the “garments” are the short tunic, or tabard, which hung over the breast-plate; the “cloak” the scarlet mantle (the chlamys of the Roman soldier), its colour probably making it a fit symbol of the zeal of Jehovah.
