Summary: Moses explained that the tribe of Levi was chosen to carry the ark, serve God, and bless in his name. Their inheritance is the Lord himself.
Moses summoned all of Israel and said to them:
At that time the LORD set apart the tribe of Levi to carry the ark of the covenant of the LORD, to stand before the LORD to minister to him, and to give blessings in his name, as they have done to this day.
For this reason, Levi has no share in the heritage with his brothers; the LORD himself is his heritage, as the LORD, your God, has told him.
