Death shall go before his face, etc… Both death and the devil shall be the executioners of his justice against his enemies: as they were heretofore against the Egyptians and Chanaanites.
3:6. He stood and measured the earth. He beheld, and melted the nations: and the ancient mountains were crushed to pieces. The hills of the world were bowed down by the journeys of his eternity.
He beheld, etc… One look of his eye is enough to melt all the nations, and to reduce them to nothing. For all heaven and earth disappear when they come before his light. Apoc. 20.11. Ibid. The ancient mountains, etc… By the mountains and hills are signified the great ones of the world, that persecute the church, whose power was quickly crushed by the Almighty.
3:7. I saw the tents of Ethiopia for their iniquity, the curtains of the land of Madian shall be troubled.
Ethiopia… the land of the Blacks, and Madian, are here taken for the enemies of God and his people: who shall perish for their iniquity.
3:8. Wast thou angry, O Lord, with the rivers? or was thy wrath upon the rivers? or thy indignation in the sea? Who will ride upon thy horses: and thy chariots are salvation.
With the rivers, etc… He alludes to the wonders wrought heretofore by the Lord in favour of his people Israel, when the waters of the rivers, viz., of Arnon and Jordan, and of the Red Sea, retired before their face: when he came as it were with his horses and chariots to save them when he took up his bow for their defence, in consequene of the oath he had made to their tribes: when the mountains trembled, and the deep stood with its waves raised up in a heap, as with hands lifted up to heaven: when the sun and the moon stood still at his command, etc., to comply with his anger, not against the rivers and sea, but against the enemies of his people. How much more will he do in favour of his Son: and against the enemies of his church?
3:9. Thou wilt surely take up thy bow: according to the oaths which thou hast spoken to the tribes. Thou wilt divide the rivers of the earth.
3:10. The mountains saw thee, and were grieved: the great body of waters passed away. The deep put forth its voice: the deep lifted up its hands.
3:11. The sun and the moon stood still in their habitation, in the light of thy arrows, they shall go in the brightness of thy glittering spear.
