Psalms 117:2
psa 117:2
This may be regarded as a doxology, suitable to be appended to any Psalm of similar character, and prophetical of the prevalence of God's grace in the world, in which aspect Paul quotes it (Rom 15:11; compare Psa 47:2; Psa 66:8). (Psa 117:1-2)
is great toward us--literally, "prevailed over" or "protected us."
