Numbers 8:20-22

20ThusH3651 did MosesH4872, and AaronH175, and all the congregationH5712 of the children of IsraelH3478, unto the LevitesH3881: according unto all that Jehovah commandedH6680 MosesH4872 touching the LevitesH3881, soH3651 did the children of IsraelH3478 unto them. 21And the LevitesH3881 purifiedH2891 themselves from sinH2398, and they washedH3526 their clothesH899: and AaronH175 offered them for a wave-offering before Jehovah; and AaronH175 made atonementH3722 for them to cleanseH2891 them. 22And after that wentH935 the LevitesH3881 in to do their serviceH5656 in the tentH168 of meetingH4150 before AaronH175, and before his sonsH1121: as Jehovah had commandedH6680 MosesH4872 concerning the LevitesH3881, soH3651 did they unto them.
