Numbers 4:18-22

18Ye shall not cutH3772 off the familiesH4940 of the KohathitesH6956 from among the LevitesH3881,

19but this shall ye do unto them, that they may liveH2421, and not dieH4191, when they drawH5066 near 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 and seeH7200 for a moment the holyH6944 thingsH6944, lest they dieH4191.

21And Jehovah spokeH1696 to MosesH4872, sayingH559,

22TakeH5375 alsoH1571 the sum of the sonsH1121 of GershonH1648, according to their fathers' housesH1004, after their familiesH4940.
