11 Behold, the ark of the covenant of the Lord of all the earth[1] is passing over before you into the Jordan. 12 Now therefore take twelve men from the tribes of Israel, from each tribe a man. 13 And when the soles of the feet of the priests bearing the ark of the Lord, the Lord of all the earth, shall rest in the waters of the Jordan, the waters of the Jordan shall be cut off from flowing, and the waters coming down from above shall stand in one heap."

14 So when the people set out from their tents to pass over the Jordan with the priests bearing the ark of the covenant before the people, 15 and as soon as those bearing the ark had come as far as the Jordan, and the feet of the priests bearing the ark were dipped in the brink of the water (now the Jordan overflows all its banks throughout the time of harvest), 16 the waters coming down from above stood and rose up in a heap very far away, at Adam, the city that is beside Zarethan, and those flowing down toward the Sea of the Arabah, the Salt Sea, were completely cut off. And the people passed over opposite 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.
