Psa 117:1

See Lesson, Psalms, “Hallelujah”.

NATIONS… PEOPLES: “Goyim” / “amim” = Gentiles and Jews. The only place in the 12 “Hallel” Psalms where the Gentiles are explicitly brought in to share in the praise of God, and — more than this — even to lead the praise. For other instances of Gentiles praising God, see Psa 57:9; 67:2,4; 72:11,17; 96:3,10; 98:2; 108:3; Isa 11:10; 42:1,6; 4;9:6; 60:3,5,11,16; 62:2; 66:19. This praise, from a variety of peoples, is echoed in Rev 7:9.

Psa 117:2

LOVE… FAITHFULNESS: “Mercy” and “truth” (AV): the covenants of promise (Psa 115:1).
