Numbers 4:16-20

16And the charge of EleazarH499 the sonH1121 of AaronH175 the priestH3548 shall be the oilH8081 for the lightH3974, and the sweet incenseH7004, and the continual meal-offering, and the anointingH4888 oilH8081, the charge of all the tabernacleH4908, and of all that therein is, the sanctuaryH6944, and the furniture thereof.

17And Jehovah spake unto MosesH4872 and unto AaronH175, sayingH559, 18CutH3772 ye not off the tribeH7626 of the familiesH4940 of the KohathitesH6956 from among the LevitesH3881; 19but thus do unto them, that they may liveH2421, and not dieH4191, when they approachH5066 unto the most holyH6944 thingsH6944: AaronH175 and his sonsH1121 shall goH935 in, and appointH7760 them every oneH376 to his serviceH5656 and to his burdenH4853; 20but they shall not goH935 in to seeH7200 the sanctuaryH6944 even for a moment, lest they dieH4191.
