Littérature du Second Temple sur La Genèse 9:21

[60] This is one form, the noblest form, of stripping or becoming naked. The other is of a contrary nature, a deprivation of virtue due to a turning or change of condition, when the soul becomes foolish and deranged. This kind of stripping is experienced by Noah, who is made naked when he has drunk wine. But, thanks be to God, the change of condition and the stripping of the mind which ensued upon the deprivation of virtue, did not spread out abroad and reach those outside, but stayed in the house, for what is said is “he was made naked in his house” (Gen. 9:21): for the wise man, if he do commit sin, does not run riot, as does the bad man. The evil of the one has been spread forth; that of the other has been held in check; so he becomes sober again, that is to say, he repents and recovers as from an illness.

Loss of virtue (another meaning given to “nakedness”) is illustrated by Noah’s lapse (Gen. 9:21). And the indications which Philo finds in the narrative that the lapse was not irretrievable are illustrated by the provision in the Law that vows made only in intent may be rescinded (Numb. 30:10).
