And I, behold, I have taken the Levites from among the children of Israel, instead of all the first-born that openeth the matrix among the children of Israel: therefore the Levites shall be mine;

Every thing that openeth the matrix in all flesh, which they bring to the LORD, whether of men or beast, shall be thine: nevertheless, the first born of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
