72:18-20 We are taught to bless God in Christ, for all he has done for us by him. David is earnest in prayer for the fulfilment of this prophecy and promise. It is sad to think how empty the earth is of the glory of God, how little service and honour he has from a world to which he is so bountiful. May we, like David, submit to Christ's authority, and partake of his righteousness and peace. May we bless him for the wonders of redeeming love. May we spend our days, and end our lives, praying for the spread of his gospel.

18, 19. These words close the Psalm in terms consistent with the style of the context, while Ps 72:20 is evidently, from its prosaic style, an addition for the purpose above explained [see on [608]Ps 72:1].
