This Psalm is also a Psalm of thanksgiving for that infinite goodness of God, his being merciful to his people; and for assuring them, by his word, and by his promises of his good will towards them; and that he will hear them, regard them, and have mercy upon them. To which immense goodness of God, no thanks of his people can be equal. And that treasure of mercy, which is greater than the whole world unto afflicted consciences,—that God freely promises to his people his blessing, in the seed of Abraham, and the remission of sins; and does not regard their unworthiness in the gift;—that treasure of mercy, I say, is greater than the mind of man is capable of conceiving. This Psalm, therefore, (if we may so speak) is properly a Psalm of the New Testament. Hence the Psalmist saith, “Sing unto the Lord a new song:” showing that all praise is to be sung unto the king of Israel and of Zion; whom all ought to laud with rejoicing, “upon their beds:” that is, in the churches and temples where they meet for worship; as the prophet Isaiah also mentions their temples, their altars, their beds, and their couches, where Israel committed fornication; that is, worshipped their idols. And that also pertains to the New Testament where the Psalmist saith, “And a two-edged sword in their hand, to execute vengeance on the heathen, and to bind their kings with chains.” This is not to be understood simply of the Jews or of the Mahometans, with respect to any earthly tyranny; but this is the vengeance promised in the scriptures; which the seed of Abraham, that is, the Israelites and the apostles, should execute by the sword of the Spirit, by which they should destroy idolatry in so many nations, and should put to shame the wisdom of the whole world, as the apostle Paul saith. 2 Cor. x. PSALM CL. _An exhortation to praise God with all kinds of instruments._ Praise ye the LORD. Praise God in his sanctuary: praise him in the firmament of his power. Praise him for his mighty acts: praise him according to his excellent greatness. Praise him with the sound of the trumpet: praise him with the psaltery and harp. Praise him with the timbrel and dance: praise him with stringed instruments and organs. Praise him upon the loud cymbals: praise him upon the high sounding cymbals. Let every thing that hath breath praise the LORD. Praise ye the LORD.
