As for God, his way is perfect: the word of the LORD is proven: he is a shield to all those that trust in him.
Read Chapter 18
Augustine of Hippo
AD 430
31. "My God, His way is undefiled "(ver. 30). My God cometh not unto men, except they shall have purified the way of faith, whereby He may come to them; for that" His way is undefiled." "The words of the Lord have been proved by fire." The words of the Lord are tried by the fire of tribulation. "He is the Protector of them that hope in Him." And all that hope not in themselves, but in Him, are not consumed by that same tribulation. For hope followeth faith.
As for, might be omitted. (Haydock)
The conduct of God towards men is irreproachable. He will treat all according to their deserts, and will fulfil his promises of protecting the just. (Eusebius)
Hebrew, "He is the strong God. His words are pure as gold. He is the shield "(Berthier)
