'Drink' in the Bible

I will recompense again, saith the Lord;' if, then, thine enemy doth hunger, feed him; if he doth thirst, give him drink; for this doing, coals of fire thou shalt heap upon his head;

Right it is not to eat flesh, nor to drink wine, nor to do anything in which thy brother doth stumble, or is made to fall, or is weak.
