Verse 3

(3) O send out thy light and thy truth: let them lead me.—Instead of the violent and contemptuous escort of Assyrian soldiers, leading the exile away from the “holy hill,” the poet prays for God’s light and truth to lead him, like two angel guides, back to it. Light and truth! What a guidance in this world of falsehood and shadow! The Urim and Thummim of the saints (Deuteronomy 33:8), the promised attendants of Israel, have been, and are, the escort of all faithful souls in all ages.

Verse 4

(4) God my God.—An expression used in this collection instead of the more usual “Jehovah my God.” (Comp. Psalms 45:7, and for its import see General Introduction, and Psalms 50:7, Note.)
