9 Take no wine, or strong drink, you or your sons with you, when you go into the Tent of meeting, that it may not be the cause of death to you; this is an order for ever through all your generations. 10 And make a division between the holy and the common, and between the unclean and the clean; 11 Teaching the children of Israel all the laws which the Lord has given them by the hand of Moses.
Matthew Henry's Commentary on Leviticus 10:9-11
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.
