[138] On which account the scripture says, "Wine and strong drink thou shalt not drink, neither thou nor thy sons after thee," when ye enter into the tabernacle of the testimony or approach the altar of sacrifice; and he goes through all these details not more by way of prohibition than of explaining his intention. In truth, for one who was issuing prohibitions, it was appropriate to say, Drink not wine when you are performing sacrifice; but for one who is declaring his opinion, it is more suitable to say, Ye shall not drink. For it is impossible for a man to admit ignorance, which is the cause of intoxication and of ignorance of the soul, if he be one who studies the generic and specific virtues and devotes himself to the pursuit of them.
