TSK · Numbers 18:2

She became pregnant again and had another son. She said,“Now this time my husband will show me affection, because I have given birth to three sons for him.” That is why he was named Levi.

You are to assign the Levites to Aaron and his sons; they will be assigned exclusively to him out of all the Israelites.

I have given the Levites as a gift to Aaron and his sons from among the Israelites, to do the work for the Israelites in the tent of meeting, and to make atonement for the Israelites, so there will be no plague among the Israelites when the Israelites come near the sanctuary.”

It was a memorial for the Israelites, that no outsider who is not a descendant of Aaron should approach to burn incense before the LORD, that he might not become like Korah and his company– just as the LORD had spoken by the authority of Moses.

They must join with you, and they will be responsible for the care of the tent of meeting, for all the service of the tent, but no unauthorized person may approach you.

They stood at their posts according to the regulations outlined in the law of Moses, the man of God. The priests were splashing the blood as the Levites handed it to them.

Then you will know that I sent this commandment to you so that my covenant may continue to be with Levi,” says the LORD of Heaven’s Armies.
