2.

This Psalm is entitled, a Psalm to be sung on the Sabbath day. Lo, this day is the Sabbath, which the Jews at this period observe by a kind of bodily rest, languid and luxurious. They abstain from labours, and give themselves up to trifles; and though God ordained the Sabbath, they spend it in actions which God forbids. Our rest is from evil works, theirs from good; for it is better to plough than to dance. They abstain from good, but not from trifling, works. God proclaims to us a Sabbath. What sort of Sabbath? First consider, where it is. It is in the heart, within us; for many are idle with their limbs, while they are disturbed in conscience....That very joy in the tranquillity of our hope, is our Sabbath. This is the subject of praise and of song in this Psalm, how a Christian man is in the Sabbath of his own heart, that is, in the quiet, tranquillity, and serenity of his conscience, undisturbed; hence he tells us here, whence men are wont to be disturbed, and he teaches thee to keep Sabbath in thine own heart.
