8 Then the Lord said to Aaron, 9 "You and your descendants must never drink wine or any other alcoholic drink before going into the Tabernacle. If you do, you will die. This is a permanent law for you, and it must be observed from generation to generation. 10 You must distinguish between what is sacred and what is common, between what is ceremonially unclean and what is clean. 11 And you must teach the Israelites all the decrees that the Lord has given them through Moses."
Matthew Henry's Commentary on Leviticus 10:8-11
Commentary on Leviticus 10:8-11
(Read Leviticus 10:8-11)
Do not drink wine or strong drink. During the time they ministered, the priests were forbidden it. It is required of gospel ministers, that they be not given to wine, 1 Timothy 3:3. It is, Lest ye die; die when ye are in drink. The danger of death, to which we are continually exposed, should engage all to be sober.
