9 Then Joshua addressed the People of Israel: "Attention! Listen to what God, your God, has to say. 10 This is how you'll know that God is alive among you - he will completely dispossess before you the Canaanites, Hittites, Hivites, Perizzites, Girgashites, Amorites, and Jebusites. 11 Look at what's before you: the Chest of the Covenant. Think of it - the Master of the entire earth is crossing the Jordan as you watch. 12 Now take twelve men from the tribes of Israel, one man from each tribe. 13 When the soles of the feet of the priests carrying the Chest of God, Master of all the earth, touch the Jordan's water, the flow of water will be stopped - the water coming from upstream will pile up in a heap."
Matthew Henry's Commentary on Joshua 3:9-13
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.
