Bede

Anger holds no mercy, etc. This is not said of all anger, for of a most mild and modest man it is written that he went out from Pharaoh in great anger (Exod. X). But he speaks of the anger of a fool, which he mentioned in the preceding verse, which loses the bowels of compassion once it has flared up, only knowing to loosen its reins in its own fury. Otherwise, useful and necessary anger is meant, Better is anger than laughter (Eccli. VII), because by the sadness of the countenance, the mind of the delinquent is corrected.
