Ambrose of Milan

If you are angry, be angry with yourselves, because you are roused, and you will not sin. For he who is angry with himself, because he has been so easily roused, ceases to be angry with another. But he who wishes to prove his anger is righteous only gets the more inflamed and quickly falls into sin. "Better is he," as Solomon says, "that restrains his anger than he that takes a city," for anger leads astray even brave men.

On the Duties of the Clergy 1.21.96 ↗

Gregory the Dialogist

For Solomon again indicates how great is the height at which the virtue of patience excels, saying: "The patient man is better than the strong man, and he who rules his spirit than he who captures cities." It is therefore a lesser victory to capture cities, because what is conquered is external. But what is conquered through patience is greater, because the mind is overcome by itself, and it subjects itself to itself, when patience prostrates it in the humility of forbearance.

Bede

Better is the patient man than the strong man, etc. It is a lesser victory to conquer cities, because they are conquered externally; but what is conquered by patience is greater, because the spirit conquers itself, and submits itself to itself, when patience brings it down in the humility of tolerance.
