7 And the Lord said to Joshua, From now on I will give you glory in the eyes of all Israel, so that they may see that, as I was with Moses, so I will be with you. 8 And you are to give orders to the priests who take up the ark of the agreement, and say, When you come to the edge of the waters of Jordan, go no further. 9 And Joshua said to the children of Israel, Come to me here: and give ear to the words of the Lord your God. 10 And Joshua said, By this you will see that the living God is among you, and that he will certainly send out from before you the Canaanite and the Hittite and the Hivite and the Perizzite and the Girgashite and the Amorite and the Jebusite. 11 See, the ark of the agreement of the Lord of all the earth is going over before you into Jordan. 12 So take twelve men out of the tribes of Israel, a man from every tribe. 13 And when the feet of the priests who take up the ark of the Lord, the Lord of all the earth, come to rest in the waters of Jordan, the waters of Jordan will be cut off, all the waters flowing down from higher up, and will come together in a mass.

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.
