17And YhwhH3068 spakeH1696 unto MosesH4872 and unto AaronH175, sayingH559, 18Cut ye not offH3772 the tribeH7626 of the familiesH4940 of the KohathitesH6956 from amongH8432 the LevitesH3881: 19But thus doH6213 unto them, that they may liveH2421, and not dieH4191, when they approachH5066 unto the mostH6944 holy thingsH6944: AaronH175 and his sonsH1121 shall go inH935, and appointH7760 them everyH376 oneH376 to his serviceH5656 and to his burdenH4853: 20But they shall not go inH935 to seeH7200 when the holy thingsH6944 are coveredH1104, lest they dieH4191.
