And blessed be the name of his majesty for ever: and the whole earth shall be filled with his majesty. So be it. So be it.

And blessed is the Name of His honour to the age, And the whole earth is filled with His honour. Amen, and amen!

Praise to the glory of his noble name for ever; let all the earth be full of his glory. So be it, So be it.

And blessed be his glorious name for ever - The name by which he is known - referring perhaps particularly to his name "Yahweh." Still the prayer would be, that all the names by which he is known, all by which he has revealed himself, might be regarded with veneration always and everywhere.
And let the whole earth be filled with his glory - With the knowledge of himself; with the manifestations of his presence; with the influences of his religion. Compare Numbers 14:21. This prayer was especially appropriate at the close of a psalm designed to celebrate the glorious reign of the Messiah. Under that reign the earth will be, in fact, filled with the glory of God; the world will be a world of glory. Assuredly all who love God, and who love mankind, all who desire that God may be honored, and that the world may be blessed and happy, will unite in this fervent prayer, and reecho the hearty "Amen and amen" of the psalmist.
Amen, and amen - So be it. Let this occur. Let this time come. The expression is doubled to denote intensity of feeling. It is the going out of a heart full of desire that this might be so.

Let the whole earth be filled with his glory - Let the Gospel - the light, the Spirit, and power of Christ, fill the world.
Amen - So let it be.
And Amen - So it shall be. Hallelujah!

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 Song 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.
