Numbers 3:11
“And the Lord spake unto Moses, saying,”
9
And thou shalt give the Levites unto Aaron and to his sons: they are wholly given unto him out of the children of Israel.
10
And thou shalt appoint Aaron and his sons, and they shall wait on their priest’s office: and the stranger that cometh nigh shall be put to death.
11
And the Lord spake unto Moses, saying,
12
And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the matrix among the children of Israel: therefore the Levites shall be mine;
13
Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the Lord.
