Adam Clarke's Bible Commentary Verse 7. For God is the King of all the earth ] He is not your King only, but the King of the universe. He has no limited power, no confined dominion.
Sing ye praises with understanding ] lykm wrmz zammeru maskil, sing an instructive song. Let sense and sound go together. Let your hearts and heads go with your voices. Understand what you sing; and feel what you understand; and let the song be what will give instruction in righteousness to them that hear it. , Sing wisely. - Anglo-Saxon. Multitudes sing foolishly.
Matthew Henry Commentary
Verses 5-9 - Praise is a duty in which we ought to be frequent and abundant. But here is a needful rule; Sing ye praises with understanding. As thos that understand why and for what reasons they praise God, and what is the meaning of the service. It is not an acceptable service, if it is not a reasonable service. We are never to forget the end of Messiah' exaltation, so continually do the prophets dwell upon the conversion of the nations to the gospel of Christ. Why do we vainly fancy that we belong to him, unless the Spirit reign in our hearts by faith? Lord, i it not thy glory and delight to give repentance to Israel and remissio of sins, now that thou art exalted as a Prince and a Saviour? Set u thy kingdom in our hearts. Bring into captivity every thought to the obedience of Christ. And so sweetly constrain all the powers an faculties of the souls of thy redeemed, into holy love, fear, an delight in thee, that praise with the understanding may rise from ever heart, both here and for ever, to Thee, our God _________________________________________________
