For God is the King of all the earth,.... Or "the king of all the earth is God" (e); the same that is ascended into heaven, and is King of saints, even Christ Jesus; and so he will appear to be, especially in the latter day; See Gill on Psa 47:2; sing ye praises with understanding; or, as De Dieu renders it, to him that understandeth, that is, to God the only wise, whose understanding is infinite; even to Christ, who, as God, knows all things; and, as man and Mediator, is of quick understanding, and has all the treasures of wisdom and knowledge in him; so R. Obadiah, "sing of him who understands"; or, "sing ye praises, O everyone that understandeth" (f); that is, how to sing, as everyone does not; this is the sense of Aben Ezra and Kimchi; or "with understanding", as we render it; with understanding of what is sung. The Apostle Paul seems to refer to this passage in Co1 14:15. The Targum renders it, "with a good understanding". (e) So Junius & Tremellius, Piscator, Cocceius, Michaelis. (f) "canite, intelligens", Montanus; i.e. "unusquisque", Vatablus.
