Matthew Henry's Commentary on Leviticus 10:10

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.
