VI. We are here directed to look up both him who is the commander-in-chief of this formidable army, and that is God himself, v. 11. It is his army; it is his camp. He raised it; he gives it commission; he utters his voice before it, as the general gives orders to his army what to do and makes a speech to animate the soldiers; it is the Lord that gives the word of command to all these animals, which they exactly observe. Some think that with this cloud of locusts God sent terrible thunder, for that is called, The voice of the Lord, and was another of the plagues of Egypt, and this made the heavens and the earth tremble. It is the day of the Lord (as it was called, v. 1), for in this war we are sure he carries the day; it must needs be his, for his camp is great and numerous. Those whom he makes war upon he can, as here, overpower with numbers; and whoever he employs to execute his word, as the minister of his justice, is sure to be made strong and par negotio—equal to what he undertakes; whom God gives commission to he girds with strength for the executing of that commission. And this makes the great day of the Lord very terrible to all those who in that day are to be made the monuments of his justice; for who can abide it? None can escape the arrests of God's wrath, can make head against the force of it, or bear up under the weight of it, 1 Sam. vi. 20; Ps. lxxvi. 7.
