Psalm 117

“Praise ye Jehovah, all ye Gentiles; laud him, all the peoples. For his mercy is powerful over us, and the truth of Jehovah [is] for everlasting. Praise ye Jah” (vers. 1, 2).
It is a short psalm out of a large heart. Grace enjoyed goes out toward others, yea to all. So will Israel then sing. What a contrast with their narrowness of old! So Jehovah's mercy and truth will work in that day to His praise on earth. We see how beautifully these three psalms ending in Hallelujah follow Psa. 114 (Jehovah's intervention as when He brought Israel out of Egypt through the desert), which is preceded by the three psalms beginning with Hallelujah, as the last of these indeed both begins and ends.
