Joshua 3:7-8

7Now the Lord said to Joshua, “This day I will begin to 1exalt you in the sight of all Israel, that they may know that just as I have been with Moses, I will be with you.

8You shall, moreover, command the priests who are carrying the ark of the covenant, saying, ‘When you come to the edge of the waters of the Jordan, you shall stand still in the Jordan.’”
