And the LORD said to Joshua, "This day I will begin to exalt you in the sight of all Israel, that they may know that, as I was with Moses, so I will be with you. And you shall command the priests who bear the ark of the covenant, 'When you come to the brink of the waters of the Jordan, you shall stand still in the Jordan.'" And when those who bore the ark had come to the Jordan, and the feet of the priests bearing the ark were dipped in the brink of the water (the Jordan overflows all its banks throughout the time of harvest), the waters coming down from above stood and rose up in a heap far off, at Adam, the city that is beside Zar'ethan, and those flowing down toward the sea of the Arabah, the Salt Sea, were wholly cut off; and the people passed over opposite Jericho. And while all Israel were passing over on dry ground, the priests who bore the ark of the covenant of the LORD stood on dry ground in the midst of the Jordan, until all the nation finished passing over the Jordan.
