Joshua 3:3 and they commanded the people, saying, “When you see the ark of the covenant of the Lord your God, and the priests, the Levites, bearing it, then you shall set out from your place and go after it. 4 Yet there shall be a space between you and it, about two thousand cubits by measure. Do not come near it, that you may know the way by which you must go, for you have not passed this way before.”

Joshua 2:23 Then the two men returned and came down from the hill country and crossed over and came to Joshua the son of Nun, and they related to him all that had happened to them. 24 They said to Joshua, “Surely the Lord has given all the land into our hands; moreover, all the inhabitants of the land have melted away before us.”
