All the earth shall worship thee,.... The Messiah, who is equal with God; the Creator of men; the Redeemer of his people; the Head of the church, and King of saints; their Lord, and therefore to be worshipped; with internal worship, in the exercise of faith, hope, and love; and with external worship, in the word and ordinances, by prayer and praise, public and private. This universal worship, that will be yielded him, will be in the latter day; which shows that this psalm respects those times, when Christ shall be King over all the earth, and his name, worship, and religion, one, Zac 14:9; and shall sing unto thee; the song of Moses and the Lamb, the Lamb's new song, the song of redeeming grace; which none but the redeemed ever can sing aright, Rev 14:3; they shall sing to thy name; or, "they shall", or "let them sing thy name" (x); thou shall be the subject of their song; thy person, offices, kingdom, grace, and glory: or they shall sing to the honour of thy name, as in Psa 66:2. Selah; on this word; see Gill on Psa 3:2. (x) "cantent nomen tuum", Gejerus; "cantabunt nomen tuum", Michaelis.
