Rejoice in the Lord, O ye righteous - This is the sentiment with which the preceding psalm closes. See the notes at Psalms 32:11.
For praise is comely for the upright - Is befitting, suitable, proper. That is, the upright - the righteous - have abundant cause for praise, and it is for them a suitable employment, or one which becomes them. A man who is upright, or who is a righteous man, has in this very fact much which lays a foundation for praise, for the fact that he has such a character is to be traced to the grace of God, and this in itself is a more valuable possession than gold or kingly crowns would he. That he is not an open violator of the law of God; that he is not intemperate; that he is not the victim of raging lusts and passions; that he is not a dishonest man; that he is not profane; that he is not an infidel or a scoffer; that he is a pious man - a redeemed man - a man of good character - an heir of heaven - is the highest blessing that could be conferred on him; and he who has been saved from outbreaking transgression and crime in a world like this, and has been enabled to live an upright life, has eminently occasion to praise and bless God. Assuredly for such a man praise is an appropriate employment, for such a man it is “comely.”
