And they commanded the people,.... In the name of Joshua, by whom they were sent:

saying, when ye see the ark of the covenant of the Lord your God, and the priests the Levites bearing it: the Targum reads, the priests and Levites; so the Septuagint: it was the business of the Levites, particularly the Kohathites, to bear the ark in journeying, but here the priests, who also were Levites, were to carry it: it is remarked in the Talmud (p), that there are three places in which the priests are said to bear the ark; here, and when they surrounded Jericho, Joshua 6:6; and when it was returned to its place in the times of David, 2 Samuel 15:29; and Kimchi and Abarbinel observe a fourth, when it was brought into Solomon's temple, 1 Kings 8:6,

then ye shall remove from your place, and go after it; their usual signal for marching was the cloud, when that was taken up, Numbers 9:17, &c. but now the ark, the clouds of glory having removed at the death of Moses, and were seen no more, as Abarbinel and other Jewish writers observe; and therefore it was proper the Israelites should be made acquainted with this signal; for, as Jarchi says, this journey was different from all the journeys (though that of the three days journey from Sinai must be excepted, Numbers 10:33), for all the time Moses was in being, the pillar of cloud marched first and showed them the way, and the ark moved after two of the standards (Judah and Reuben), and now the ark went first: the cloud was a figure of the dark and cloudy dispensation of the law, particularly the ceremonial law, the shadow of good things to come, and which continued only during the former state, and discontinued to be of any use when the Mosaic dispensation ceased, and when Joshua or Jesus was come: the ark was a type of Christ, the forerunner for us entered, and whom we are to follow whithersoever he goes or directs to, in the exercise of grace and performance of duty; and the ark being carried now by different persons, may denote that Christ was held forth in a weaker manner under the legal dispensation, and by his apostles and ministers under the Gospel dispensation in a clearer and stronger manner, and who are to be followed no further or longer than as they bear the ark or direct to Christ.

And they commanded the people, saying, When ye see the ark of the covenant of the LORD your God, and the priests the Levites bearing it, then ye shall remove from your place, and go after it.

3:3 Commanded the people - In Joshua's name, and by his authority. Priests and Levites - Who were not only Levites, but priests also. For altho' the Levites were to carry the ark, Numb 4:1 - 15, yet the priests might perform that office, and did so upon some solemn occasions. Go after it - Towards Jordan, to go over it in such a manner as I am about to describe. 'Till this time the ark went in the middle of the cloudy pillar, now it goes in the front. Probably the pillar of fire and cloud was still hovering over the ark.

3, 4. When ye see the ark ., and the priests the Levites bearing it-The usual position of the ark, when at rest, was in the center of the camp; and, during a march, in the middle of the procession. On this occasion it was to occupy the van, and be borne, not by the Kohathite Levites, but the priests, as on all solemn and extraordinary occasions (compare Nu 4:15; Jos 6:6; 1Ki 8:3-6).

then ye shall . go after it. Yet there shall be a space between you and it-These instructions refer exclusively to the advance into the river. The distance which the people were to keep in the rear of the ark was nearly a mile. Had they crowded too near the ark, the view would have been intercepted, and this intervening space, therefore, was ordered, that the chest containing the sacred symbols might be distinctly visible to all parts of the camp, and be recognized as their guide in the untrodden way.

3:1-6 The Israelites came to Jordan in faith, having been told that they should pass it. In the way of duty, let us proceed as far as we can, and depend on the Lord. Joshua led them. Particular notice is taken of his early rising, as afterwards upon other occasions, which shows how little he sought his own ease. Those who would bring great things to pass, must rise early. Love not sleep, lest thou come to poverty. All in public stations should always attend to the duty of their place. The people were to follow the ark. Thus must we walk after the rule of the word, and the direction of the Spirit, in everything; so shall peace be upon us as upon the Israel of God; but we must follow our ministers only as they follow Christ. All their way through the wilderness was an untrodden path, but most so this through Jordan. While we are here, we must expect and prepare to pass ways that we have not passed before; but in the path of duty we may proceed with boldness and cheerfulness. Whether we are called to suffer poverty, pain, labour, persecution, reproach, or death, we are following the Author and Finisher of our faith; nor can we set our feet in any dangerous or difficult spot, through our whole journey, but faith will there see the prints of the Redeemer's feet, who trod that very path to glory above, and bids us follow him, that where he is, we may be also. They were to sanctify themselves. Would we experience the effects of God's love and power, we must put away sin, and be careful not to grieve the Holy Spirit of God.
