Numbers 3:5-13 - The Assignment Of The Levites

⁵ And the Lord said to Moses, ⁶ Make the tribe of Levi come near, and put them before Aaron the priest, to be his helpers, ⁷ In order that they may be responsible to him and to all Israel for the care of the Tent of meeting, and to do the work of the House; ⁸ And they will have the care of all the vessels of the Tent of meeting, and will do for the children of Israel all the necessary work of the House. ⁹ Give the Levites to Aaron and his sons; so that they may be his without question from among the children of Israel. ¹⁰ And give orders that Aaron and his sons are to keep their place as priests; any strange person who comes near is to be put to death.

¹¹ And the Lord said to Moses, ¹² See, I have taken the Levites out of the children of Israel to be mine in place of the first sons of the children of Israel; ¹³ For all the first sons are mine; on the day when I put to death all the first sons in the land of Egypt, I took for myself every first male birth of man and beast. They are mine; I am the Lord.
