And you shall know, recognize, and understand that I have sent this [new] decree to you priests, to be My [new] covenant with Levi [the priestly tribe], says the Lord of hosts.
At that time the Lord set apart the tribe of Levi to bear the ark of the covenant of the Lord, to stand before the Lord to minister to Him and to bless in His name unto this day.
Then the Tent of Meeting shall set out, with the camp of the Levites in the midst of the camps; as they encamp so shall they set forward, every man in his place, standard after standard.
So they shall keep charge of the Tent of Meeting and the Holy Place and shall attend to the sons of Aaron their kinsmen, for the service of the house of the Lord.
And they set the priests in their divisions and the Levites in their courses for the service of God at Jerusalem, as it is written in the Book of Moses.
And, behold, I have given the Levites all the tithes in Israel for an inheritance in return for their service which they serve, the [menial] service of the Tent of Meeting.
But their duty should be to wait on [the priests] the sons of Aaron in the service of the house of the Lord, caring for the courts, the chambers, the cleansing of all holy things, and any work of the service of God's house,
