11 the ark of the covenant of the Lord of all the earth is going to pass before you into the Jordan. 12 So now select twelve men from the tribes of Israel, one from each tribe. 13 When the soles of the feet of the priests who bear the ark of the Lord, the Lord of all the earth, rest in the waters of the Jordan, the waters of the Jordan flowing from above shall be cut off; they shall stand in a single heap."

14 When the people set out from their tents to cross over the Jordan, the priests bearing the ark of the covenant were in front of the people. 15 Now the Jordan overflows all its banks throughout the time of harvest. So when those who bore the ark had come to the Jordan, and the feet of the priests bearing the ark were dipped in the edge of the water, 16 the waters flowing from above stood still, rising up in a single heap far off at Adam, the city that is beside Zarethan, while those flowing toward the sea of the Arabah, the Dead Sea, were wholly cut off. Then the people crossed 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.
