Leeser(i)
16 For they are wholly given unto me from the midst of the children of Israel: instead of every one that openeth the womb, of every first-born of the children of Israel, have I taken them unto me.
17 For mine are all the first-born of the children of Israel, both of man and beast: on the day that I smote every first-born in the land of Egypt did I sanctify them unto myself.
18 And I have taken the Levites, instead of all the first-born among the children of Israel.
19 And I have given the Levites as a gift to Aaron and to his sons from the midst of the children of Israel, to do the service of the children of Israel in the tabernacle of the congregation, and to make an atonement for the children of Israel; that there be no plague among the children of Israel, when the children of Israel come nigh unto the sanctuary.
