IV. The priests were ordered to take up the ark and carry it before the people, v. 6. It was the Levites' work ordinarily to carry the ark, Num. iv. 15. But on this great occasion the priests were ordered to do it. And they did as they were commanded, took up the ark, and did not think themselves disparaged, went before the people, and did not think themselves exposed; the ark they carried was both their honour and their defence. And now we may suppose that prayer of Moses used, when the ark set forward (Num. x. 35), Rise up, Lord and let they enemies be scattered. Magistrates are here instructed to stir up ministers to their work, and to make use of their authority for the furtherance of religion. Ministers must likewise learn to go before in the way of God, and not to shrink nor draw back when dangers are before them. They must expect to be most struck at, but they know whom they have trusted.
