Numbers 8:13-18

13And thou shalt setH5975 the LevitesH3881 before AaronH175, and before his sonsH1121, and offer them as a wave-offering to Jehovah.

14And thou shalt separateH914 the LevitesH3881 from among the children of IsraelH3478, that the LevitesH3881 may beH1961 mine.

15And afterwards shall the LevitesH3881 comeH935 in to do the service of the tentH168 of meetingH4150. And thou shalt cleanseH2891 them, and offer them as a wave-offering.

16For they are wholly givenH5414 unto me from among the children of IsraelH3478; instead of every one that breaketh open the wombH7358, instead of every firstbornH1060 among the children of IsraelH3478, have I takenH3947 them unto me.

17For all the firstbornH1060 among the children of IsraelH3478 are mine, both of manH120 and beast; on the dayH3117 that I smote every firstbornH1060 in the landH776 of EgyptH4714, I hallowed them to myself.

18And I have takenH3947 the LevitesH3881 instead of all the firstbornH1060 among the children of IsraelH3478.
