Ezekiel 44:21

Neither shall any priest drink wine
That is, to excess, immoderately, so as to be inebriated with it, ( Leviticus 10:9-11 ) , should not be given to it, and greedy of it, and drink it so as to disguise themselves: this is reckoned among the qualifications of a Gospel minister, ( 1 Timothy 3:3 ) , otherwise it is not forbidden good men, or ministers of the word, to drink wine, for health's sake, and for the refreshment of nature, provided it is done in moderation, ( 1 Timothy 5:23 ) , and particularly care should be taken that they drink it in such a manner, when they enter into the inner court:
to attend divine service, since immoderate drinking affects the memory; and such may forget the law and doctrines of the Lord they are to deliver or hear; and may put them upon saying and doing that which is improper and indecent: drunkenness in any Christian professor is abominable, especially in a minister of the word; and when it appears in his ministration, it is scandalous to the last degree.
