Let them praise his name in the dance - במחול bemachol, with the pipe, or some kind of wind music, classed here with תף toph, the tabor or drum, and כנור kinnor, the harp." מחול machol," says Parkhurst, "some fistular wind-instrument of music, with holes, as a flute, pipe, or fife, from חל chal, to make a hole or opening." I know no place in the Bible where מחול machol and מחלת machalath mean dance of any kind; they constantly signify some kind of pipe.
The sound of the trumpet - שופר sophar, from its noble, cheering, and majestic sound; for the original has this ideal meaning.
With the psaltery - נבל nebel ; the nabla, a hollow stringed instrument; perhaps like the guitar, or the old symphony.
And harp - כנור kinnor, another stringed instrument, played on with the hands or fingers.
Lo, children are an heritage of the Lord - They are an inheritance derived from the Lord. They are bestowed by him as really as success is in building a house, or in guarding a city. The idea is, that everything which we value, or which we desire, is a gift from God, and is to be received as from him, and to be acknowledged as his gift. The general idea here, as in the previous verses, is that of entire dependence on God.
And the fruit of the womb is his reward - Or rather, “a reward;” that is, they are of the nature of a reward for a life of devotion to God; they are among the blessings which God promises, and are evidences of his favor. Our translation by inserting the words “is his” obscures the sense, as if the meaning were that they belong to God as his “reward” for what he does for us. The reverse of this is the true idea - that they are a blessing with which he rewards or favors his people. Of course, this is not universally true, but the promise is a general one, in accordance with the usual promises in the Bible in regard to the result of piety. Children are to be reckoned among the divine favors bestowed on us, and for their lives, their health, their virtues, and the happiness derived from them, we are, as in other things, dependent on him - as in building a house, in guarding a city, or in the rest and comfort derived from toil.
