Albert Barnes Commentary Psalms 118:2

"Let Israel now say, That his lovingkindness [endureth] for ever." — Psalms 118:2 (ASV)

Let Israel now say ... — The Hebrew people; the people of God. They have now, in my case, a new illustration of the mercy of God which ought to animate them, and to encourage their hearts. Compare (Psalms 115:9).
