Joshua 3:3-4

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. 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.”

Ezra 7:9

On the first day of the first month he began his journey from Babylon, and on the first day of the fifth month he came to Jerusalem, according to the good hand of his God upon him.
