¹³ You shall set the Levites before Aaron, and before his sons, and offer them as a wave offering to Yahweh.

¹⁵ "After that, the Levites shall go in to do the service of the Tent of Meeting: and you shall cleanse them, and offer them as a wave offering.

¹² "Behold, I have taken the Levites from among the children of Israel instead of all the firstborn who open the womb among the children of Israel; and the Levites shall be mine:

¹² the same shall purify himself therewith on the third day, and on the seventh day he shall be clean: but if he doesn't purify himself the third day, then the seventh day he shall not be clean.

¹⁹ and the clean person shall sprinkle on the unclean on the third day, and on the seventh day: and on the seventh day he shall purify him; and he shall wash his clothes, and bathe himself in water, and shall be clean at even.
