Numbers 8:17-19 ▼

17 For Mine are all the firstborn among the sons of Israel, the man and the beast. On the day that I struck all the firstborn in the land of Egypt, I sanctified them to Myself.

18 And I have taken the Levites instead of all the firstborn of the sons of Israel.

19 And I have given the Levites as a gift to Aaron and his sons from the midst of the sons of Israel, to do the work of the sons of Israel in the Tent of Meeting, and to make atonement upon the sons of Israel, and there will be no plague among the sons of Israel at the coming of the sons of Israel to the sanctuary.”
