Joshua 3:9-13

And Joshua said unto the children of Israel, Come hither, and hear the words of Jehovah your God. And Joshua said, Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanite, and the Hittite, and the Hivite, and the Perizzite, and the Girgashite, and the Amorite, and the Jebusite. Behold, the ark of the covenant of the Lord of all the earth passeth over before you into the Jordan. Now therefore take you twelve men out of the tribes of Israel, for every tribe a man. And it shall come to pass, when the soles of the feet of the priests that bear the ark of Jehovah, the Lord of all the earth, shall rest in the waters of the Jordan, that the waters of the Jordan shall be cut off, even the waters that come down from above; and they shall stand in one heap.
