Numbers 3:5-13 (NKJV)
[5] And the Lord spoke to Moses, saying:
[6] “Bring the tribe of Levi near, and present them before Aaron the priest, that they may serve him. [7] And they shall attend to his needs and the needs of the whole congregation before the tabernacle of meeting, to do the work of the tabernacle.
[8] Also they shall attend to all the furnishings of the tabernacle of meeting, and to the needs of the children of Israel, to do the work of the tabernacle.
[9] And you shall give the Levites to Aaron and his sons; they are given entirely to him from among the children of Israel.
[10] So you shall appoint Aaron and his sons, and they shall attend to their priesthood; but the outsider who comes near shall be put to death.”
[11] Then the Lord spoke to Moses, saying:
[12] “Now behold, I Myself have taken the Levites from among the children of Israel instead of every firstborn who opens the womb among the children of Israel. Therefore the Levites shall be Mine,
[13] because all the firstborn are Mine. On the day that I struck all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, both man and beast. They shall be Mine: I am the Lord.”
