Let them praise thy great and terrible name - The word rendered "terrible" means "to be feared or reverenced;" that is, his name - his being - he himself - is suited to inspire awe and reverence. The word "them" here refers to the nations over whom God reigns. It is a call on them to praise their king and their God.
For it is holy - See the notes at Isaiah 6:3; notes at Revelation 4:8. The fact that God "is" holy - that he is pure and righteous - that he cannot look upon sin but with abhorrence - is a just foundation for universal praise. Who could worship or honor a God who was not pure and holy?
Let them praise thy great and terrible name - Let them confess thee to be great and terrible: let them tremble before thee.
For it is holy - קדוש הוא kadosh hu. As this not only ends this verse but the fifth also, and in effect the ninth, it seems to be a species of chorus which was sung in a very solemn manner at the conclusion of each of these parts. His holiness - the immaculate purity of his nature, was the reason why he should be exalted, praised, and worshipped.
Let them (b) praise thy great and terrible name; [for] it [is] holy.
(b) Though the wicked rage against God, the godly will praise his Name and mighty power.
Let them praise thy great and terrible name,.... All people, especially the Lord's people; those that dwell in Zion, where his name is great, in high esteem, venerable, and valued; as his name Jesus, or Saviour, is amiable and lovely to his saints; and his name, the Lion of the tribe of Judah, is terrible to his enemies:
for it is holy; his name is holy, as well as reverend and great; his nature is holy, both divine and human; holy in all his ways and works; and is holiness to his people, and therefore worthy of praise; holiness is the ground and foundation of his praise from the seraphim, Isaiah 6:3.
thy . . . name--perfections of justice, power, &c.
great and terrible name--producing dread (Deuteronomy 10:17), and to be praised by those over whom He is exalted (Psalm 97:9).
it is holy--or, "He is holy" (Psalm 99:5, Psalm 99:9; Isaiah 6:3).
