Rejoice in the Lord, O ye righteous,.... See Gill on Psa 32:11; for praise is comely for the upright; it becomes them; it is their duty; they are bound unto it by the mercies and favours they have received; should they not give praise to God, the stones of the wall would cry out, and rebuke them for their ingratitude: it is beautiful, and looks lovely in them; it is an ornament to them, and is, in the sight of God, of great esteem: it is very acceptable to him, and when grace is in exercise, and their hearts in tune, being sensibly touched and impressed with the goodness of God, it is desirable by them, and is pleasant and delightful to them.
