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.
And the firstling of an ass thou shalt redeem with a lamb: and if thou wilt not redeem it, then thou shalt break its neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.
And I, behold, I have taken your brethren the Levites from among the children of Israel: to you they are a gift, given unto the LORD, to do the service of the tent of meeting.
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 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.
