Take the Levites in place of all the first sons of the children of Israel, and the cattle of the Levites in place of their cattle; the Levites are to be mine; I am the Lord.
A lamb may be given in payment for the young of an ass, but if you will not make payment for it, its neck will have to be broken. For all the first of your sons you are to make payment. No one is to come before me without an offering.
Now, see, I have taken your brothers the Levites from among the children of Israel: they are given to you and to the Lord, to do the work of the Tent of meeting.
For they have been given to me from among the children of Israel; in place of every mother's first son, the first to come to birth in Israel, I have taken them for myself.
