Psalms 80:3

Turn us again Usually taken to mean bring us backfrom exile, or more generally, restore us:repair our broken fortunes. Cp. Psalms 60:1. But is it not rather an allusion to Ephraim's prayer in Jeremiah 31:18, interpreted in Lamentations 5:21 in a spiritual sense? National repentance is the condition of national restoration; and it must be God's own work. Make us return to Thee, and return to us (Psalms 80:14) with Thy favour as of old; then and not till then shall we be saved.

cause thy face to shine Shew us Thy favour as of old: words borrowed from the great Aaronic benediction, Numbers 6:25. Cp. Psalms 4:6.
