Sing unto God, ye kingdoms of the earth Not only Egypt and Ethiopia, but other kingdoms and nations also, who shall partake of the same grace with them. To him that rideth upon the heavens of heavens Upon the highest heavens, his truest and best sanctuary; dwelling there in infinite glory and majesty, and from thence looking down upon all the inhabitants of the earth, and ruling them by his almighty power, and therefore most fit to be acknowledged and received by all kings and kingdoms as their Lord and Governor; which were of old From the very beginning of the world; whereas the ark was only a few hundreds of years old. Lo, he doth send out his voice Thunder is described in Scripture as the voice of God, (Psalms 29.,) and is peculiarly awful and terrible in the eastern and warmer parts of the earth. But the word of God seems to be here meant, namely, the gospel, published by Christ and his apostles, with the Holy Ghost sent down from heaven; which might well be called God's voice, and that a mighty voice, because it produced such great and wonderful effects, as are here mentioned, in converting the kings and kingdoms of the earth.
