Joshua 3:9-13

Then Joshua said to the sons of Israel, “Come here, and hear the words of the LORD your God.” Joshua said, “By this you shall know that the living God is among you, and that He will assuredly dispossess from before you the Canaanite, the Hittite, the Hivite, the Perizzite, the Girgashite, the Amorite, and the Jebusite. Behold, the ark of the covenant of the Lord of all the earth is crossing over ahead of you into the Jordan. Now then, take for yourselves twelve men from the tribes of Israel, one man for each tribe. It shall come about when the soles of the feet of the priests who carry the ark of the LORD, the Lord of all the earth, rest in the waters of the Jordan, the waters of the Jordan will be cut off, and the waters which are flowing down from above will stand in one heap.”
