From the title of this Psalm, it should seem more than probable that it was composed for the public service of the temple on the sabbath-day. But whether this was the case or not, it is now marked by the Holy Ghost as suitable for the Lord's-day service, and may, under his teaching, be happily made use of either in private or public. Every sabbath day is, or ought to be, a thanksgiving day. And as it is the Lord's day, and an emblem of the Lord's rest, believers ought, with particular reference to Christ, to enjoy both the Lord and his day. And, Reader, do observe, that though it be called a Psalm, or Song, for the Sabbath, yet is it not confined to that day; for the hymn saith, it is blessed to show forth the loving-kindness of the Lord in the morning, and his faithfulness every night. And as we have no psaltery nor harp suited to the Old Testament dispensation, I would say, Lord let the ten strings of my instrument be the whole chords of my heart. Tune the whole to praise thee, to love thee, to celebrate thy goodness, and out of the abundance of my heart may my lips to glorify thee!
