Philo: Allegorical Interpretation, III

XLII. (123) Moses, therefore, says that discreet discourse, having its own peculiar virtues, is placed on the breast of Aaron, that is to say, of anger, in order that it may in the first instance be guided by reason, and may not be injured by its own deficiency in reason, and, in the second place, by distinctness, for there is no natural influence which makes anger a friend to distinctness. At all events, not only are the ideas of angry men, but all their expressions also, full of disorder and confusion, and therefore it is very natural for the want of clearness on the part of anger to be rectified by clearness, (124) and, in addition, by truth; for, among other things, anger has also this particular property of being inclined to misrepresent the truth.

At all events, of all those who give way to this disposition scarcely any one speaks the strict truth, as if it were his soul and not his body that is under the influence of its intoxication. These, then, are the chief remedies suitable for that part of the soul which is influenced by anger, namely, reason, disinterestedness of language, and truth of language, for the three things are in power only one, namely, reason, curing anger, which is a pernicious disease of the soul, by means of the virtues truth and perspicuity.
