For they are wholly given unto me from among the children of Israel; instead of all that openeth the womb, even the firstborn of all the children of Israel, have I taken them unto me.
And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the womb among the children of Israel; and the Levites shall be mine:
for all the firstborn are mine; 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 they shall be; I am the LORD.
Take the Levites instead of all the firstborn among the children of Israel, and the cattle of the Levites instead of their cattle: and the Levites shall be mine; I am the LORD.
