Adam Clarke's Bible Commentary Verse 2. Praise the Lord with harp ] rwnk kinnor; probably something like our harp: but Calmet thinks it the ancient testudo, or lyre with three strings.
The psalter ] lbn nebel. Our translation seems to make a third instrument in this place, by rendering rw[ asor, an instrument of ten strings; whereas they should both be joined together, for rw[ lbn nebel-asor signifies the nebal, or nabla, with ten strings, or holes. Calmet supposes this to have resembled our harp. In one of Kennicott's MSS., this Psalm begins with the second verse.
Matthew Henry Commentary
Verses 1-11 - Holy joy is the heart and soul of praise, and that is here pressed upo the righteous. Thankful praise is the breath and language of holy joy Religious songs are proper expressions of thankful praise. Ever endowment we possess, should be employed with all our skill an earnestness in God's service. His promises are all wise and good. Hi word is right, and therefore we are only in the right when we agre with it. His works are all done in truth. He is the righteous Lord therefore loveth righteousness. What a pity it is that this earth which is so full of the proofs and instances of God's goodness, shoul be so empty of his praises; and that of the multitudes who live upo his bounty, there are so few who live to his glory! What the Lord does he does to purpose; it stands fast. He overrules all the counsels of men, and makes them serve his counsels; even that is fulfilled, whic to us is most surprising, the eternal counsel of God, nor can any thin prevent its coming to pass.
