11 Behold, the ark of the covenant of the Lord of all the earth passes over before you into the Jordan. 12 Now therefore take twelve men out of the tribes of Israel, for every tribe a man. 13 It shall come to pass, when the soles of the feet of the priests who bear the ark of Yahweh, the Lord of all the earth, rest in the waters of the Jordan, that the waters of the Jordan will be cut off, even the waters that come down from above; and they shall stand in one heap.”

14 It happened, when the people moved from their tents to pass over the Jordan, the priests who bore the ark of the covenant being before the people, 15 and when those who bore the ark had come to the Jordan, and the feet of the priests who bore the ark had dipped in the edge of the water (for the Jordan overflows all its banks all the time of harvest), 16 that the waters which came down from above stood, and rose up in one heap, a great way off, at Adam, the city that is beside Zarethan; and those that went down toward the sea of the Arabah, even the Salt Sea, were wholly cut off. Then the people passed over right against Jericho.

Matthew Henry's Commentary on Joshua 3:11-16

Commentary on Joshua 3:7-13

(Read Joshua 3:7-13)

The waters of Jordan shall be cut off. This must be done in such a way as never was done, but in the dividing of the Red sea. That miracle is here repeated; God has the same power to finish the salvation of his people, as to begin it; the WORD of the Lord was as truly with Joshua as with Moses. God's appearances for his people ought to encourage faith and hope. God's work is perfect, he will keep his people. Jordan's flood cannot keep out Israel, Canaan's force cannot turn them out again.

Commentary on Joshua 3:14-17

(Read Joshua 3:14-17)

Jordan overflowed all its banks. This magnified the power of God, and his kindness to Israel. Although those who oppose the salvation of God's people have all advantages, yet God can and will conquer. This passage over Jordan, as an entrance to Canaan, after their long, weary wanderings in the wilderness, shadowed out the believer's passage through death to heaven, after he has finished his wanderings in this sinful world. Jesus, typified by the ark, hath gone before, and he crossed the river when it most flooded the country around. Let us treasure up experiences of His faithful and tender care, that they may help our faith and hope in the last conflict.
