Bamidbar 8:15-17

Orthodox Jewish Bible

¹⁵ And after that shall the Levi’im go in to do the service of the Ohel Mo’ed; and thou shalt make them tahor and offer them for a tenufah.

¹⁶ For they are wholly given unto Me from among the Bnei Yisroel; instead of such as open every womb, even instead of the Bechor Kol Bnei Yisroel, have I taken them unto Me.

¹⁷ For Kol Bechor Bnei Yisroel are Mine, both adam and behemah; on the day that I struck down kol bechor in Eretz Mitzrayim I set them apart as kodesh for Myself.
