(5) Sing . . .--Rather, Play to Jehovah on a harp. on a harp, and with melodious sound of music.

Verse 5. - Sing unto the Lord with the harp; i.e. "with a harp accompaniment." It is fitting that in the praises of God instrumental music should be joined with vocal melody (comp. Exodus 15:20; 2 Samuel 6:15; 1 Chronicles 15:16, 28; 1 Chronicles 16:6; 2 Chronicles 5:12, 13; Ezra 3:10; Nehemiah 12:27, etc.). With the harp, and the voice of a psalm; or, the voice of melody (Revised Version).

98:4-9 Let all the children of men rejoice in the setting up the kingdom of Christ, for all may benefit by it. The different orders of rational creatures in the universe, seem to be described in figurative language in the reign of the great Messiah. The kingdom of Christ will be a blessing to the whole creation. We expect his second coming to begin his glorious reign. Then shall heaven and earth rejoice, and the joy of the redeemed shall be full. But sin and its dreadful effects will not be utterly done away, till the Lord come to judge the world in righteousness. Seeing then that we look for such things, let us give diligence that we may be found of him in peace, without spot, and blameless.Sing unto the Lord with the harp,.... Playing upon that at the same time: here and in the following verse is an allusion to Old Testament worship, and the manner of performing that; not that this should be done in New Testament times, only New Testament worship is expressed in Old Testament language, which is no unusual thing; hence in Gospel times, and Gospel churches, the saints, especially when singing the new song of redeeming grace, are said to have harps in their hands, expressive only of their spiritual melody in their hearts, Revelation 5:8,

with the harp, and the voice of the psalm; with the harp alone first, as Aben Ezra and Kimchi interpret it, and then with the harp, and together with the words of a psalm, sung in a psalm tune. Gospel churches are to sing psalms, hymns, and spiritual songs, Ephesians 5:19.
