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.And blessed be his glorious name for ever,.... Every name of Christ is glorious in itself, and precious to his people; "like ointment poured forth", as his name Messiah, to which the allusion is in Sol 1:3; his name Immanuel, God with us, Isaiah 7:14; Jehovah our righteousness, Jeremiah 23:6; Jesus a Saviour; as well as what belongs to his royal dignity, King of kings, and Lord of lords; a name above every name that is named in this world, or that to come;

and let the whole earth be filled with his glory; as it will be, when his kingdom shall be from sea to sea, and from the river to the ends of the earth; when the little stone cut out without hands shall become a great mountain, and fill the whole earth; when the Gospel shall be spread all over the world; and the earth be filled with the knowledge of Christ, by means of it, as the waters cover the sea; and when all nations shall come and worship before him.

Amen, and Amen; which word added is expressive of the desires of the psalmist, that all that he had said might come to pass; and of his faith, that so it would be: and it is repeated to show the vehemence of his desires, and the strength of his faith.
