Yehoshua (Joshua) 3:1-6

And Yehoshua rose early in the morning, and they set out from Shittim and came to the Yardĕn, he and all the children of Yisra’ĕl, and stayed there before they passed over. And it came to be, after three days, that the officers went into the midst of the camp, and they commanded the people, saying, “When you see the ark of the covenant of יהוה your Elohim, and the priests, the Lĕwites, bearing it, then you shall set out from your place and follow it. “Only, keep a distance between you and it, about two thousand cubits by measure. Do not come near it, so that you know which way to go, for you have not passed over this way before.” And Yehoshua said to the people, “Set yourselves apart, for tomorrow יהוה is doing wonders in your midst.” And Yehoshua spoke to the priests, saying, “Take up the ark of the covenant and pass over before the people.” So they took up the ark of the covenant and went before the people.
