Philo Judaeus De Ebrietate 2

[2] for in many places of his history of the giving of the law he mentions wine, and the plant which produces wine, namely the vine; and he commands some persons drink it, but some he does not permit to do so; and at times he gives contrary directions to the same people, ordering them sometimes to drink and some times to abstain. These therefore are the persons who have taken the great vow, to whom it is expressly forbidden to drink unmixed wine, being the priests who are engaged in offering sacrifices. But those who drink wine are numerous beyond all calculation, and among them are all those who are especially praised by the lawgiver for their virtue.
