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.

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?

great and terrible name-producing dread (De 10:17), and to be praised by those over whom He is exalted (Ps 97:9).

it is holy-or, "He is holy" (Ps 99:5, 9; Isa 6:3).

99:1-5 God governs the world by his providence, governs the church by his grace, and both by his Son. The inhabitants of the earth have cause to tremble, but the Redeemer still waits to be gracious. Let all who hear, take warning, and seek his mercy. The more we humble ourselves before God, the more we exalt him; and let us be thus reverent, for he is holy.
