And when those beasts {c} give glory and honour and thanks to him that sat on the throne, who liveth for ever and ever,

(c) God is said to have glory, honour, kingdom, and such like given to him, when we godly and reverently set forth that which is properly and only his.

People's New Testament

4:9 And when those beasts give glory and honour and thanks to him. Shall utter such praises as are given in Re 4:8. Then the twenty-four elders also join in swelling the anthems. It will be noted that these two classes, whatever they signify, are both about the throne, and both engage in harmonious praise of the Almighty.

Wesley's Notes

4:9-10 And when the living creatures give glory - the elders fall down - That is, as often as the living creatures give glory, immediately the elders fall down. The expression implies, that they did so at the same instant, and that they both did this frequently. The living creatures do not say directly, Holy, holy, holy art thou; but only bend a little, out of deep reverence, and say, Holy, holy, holy is the Lord. But the elders, when they are fallen down, may say, Worthy art thou, O Lord our God.

Jamieson-Fausset-Brown Bible Commentary

9-11. The ground of praise here is God's eternity, and God's power and glory manifested in the creation of all things for His pleasure. Creation is the foundation of all God's other acts of power, wisdom, and love, and therefore forms the first theme of His creatures' thanksgivings. The four living creatures take the lead of the twenty-four elders, both in this anthem, and in that new song which follows on the ground of their redemption (Re 5:8-10).

when-that is, whensoever: as often as. A simultaneous giving of glory on the part of the beasts, and on the part of the elders.

Matthew Henry's Concise Commentary

4:9-11 All true believers wholly ascribe their redemption and conversion, their present privileges and future hopes, to the eternal and most holy God. Thus rise the for-ever harmonious, thankful songs of the redeemed in heaven. Would we on earth do like them, let our praises be constant, not interrupted; united, not divided; thankful, not cold and formal; humble, not self-confident.
