11 Behold, the ark of the covenant of the Lord of all the earth is crossing over before you into the Jordan. 12 Now therefore, take for yourselves twelve men from the tribes of Israel, one man from every tribe. 13 And it shall come to pass, as soon as the soles of the feet of the priests who bear the ark of the Lord, the Lord of all the earth, shall rest in the waters of the Jordan, that the waters of the Jordan shall be cut off, the waters that come down from upstream, and they shall stand as a heap."
14 So it was, when the people set out from their camp to cross over the Jordan, with the priests bearing the ark of the covenant before the people, 15 and as those who bore the ark came to the Jordan, and the feet of the priests who bore the ark dipped in the edge of the water (for the Jordan overflows all its banks during the whole time of harvest), 16 that the waters which came down from upstream stood still, and rose in a heap very far away at Adam, the city that is beside Zaretan. So the waters that went down into the Sea of the Arabah, the Salt Sea, failed, and were cut off; and 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.
