Webster(i)
14 Thus shalt thou separate the Levites from among the children of Israel: and the Levites shall be mine.
15 And after that shall the Levites go in to perform the service of the tabernacle of the congregation: and thou shalt cleanse them, and offer them for an offering.
16 For they are wholly given to me from among the children of Israel; instead of such as open every womb, even instead of the first-born of all the children of Israel, have I taken them to me.
