Numbers 18:5-7

5And you shall attendH8104 to the dutiesH4931 of the sanctuaryH6944 and of the altarH4196, so that wrathH7110 may notH3808 fallH1961 onH5921 the IsraelitesH1121H3478 againH5750. 6BeholdH2009, I MyselfH589 have selectedH3947 your fellowH251 LevitesH3881 fromH8432 the IsraelitesH1121H3478 as a giftH4979 to you, dedicatedH5414 to the LORDH3068 to performH5647 the serviceH5656 for the TentH168 of MeetingH4150. 7But only youH859 and your sonsH1121H854 shall attendH8104 to your priesthoodH3550 for everythingH3605 concerningH1697 the altarH4196 and what is insideH1004 the veilH6532, and you are to perform that serviceH5647. I am givingH5414 you the workH5656 of the priesthoodH3550 as a giftH4979, but any outsiderH2114 who comes nearH7131 the sanctuary must be put to deathH4191.”
