Numbers 8:11-18

11and AaronH175 shall offer the LevitesH3881 before Jehovah for a wave-offering, on the behalf of the children of IsraelH3478, that it may beH1961 theirs to do the serviceH5656 of Jehovah. 12And the LevitesH3881 shall lay their handsH3027 upon the headsH7218 of the bullocks: and offerH6213 thou the oneH259 for a sin-offering, and the other for a burnt-offering, unto Jehovah, to makeH6213 atonementH3722 for the LevitesH3881. 13And thou shalt setH5975 the LevitesH3881 before AaronH175, and before his sonsH1121, and offer them for a wave-offering unto Jehovah.

14Thus shalt thou separateH914 the LevitesH3881 from among the children of IsraelH3478; and the LevitesH3881 shall beH1961 mine. 15And after that shall the LevitesH3881 goH935 in to do the service of the tentH168 of meetingH4150: and thou shalt cleanseH2891 them, and offer them for a wave-offering. 16For they are wholly givenH5414 unto me from among the children of IsraelH3478; instead of all that openeth the wombH7358, even the first-born of all the children of IsraelH3478, have I takenH3947 them unto me. 17For all the first-born among the children of IsraelH3478 are mine, both manH120 and beast: on the dayH3117 that I smote all the first-born in the landH776 of EgyptH4714 I sanctifiedH6942 them for myself. 18And I have takenH3947 the LevitesH3881 instead of all the first-born among the children of IsraelH3478.
