We see a good example of self-control implied in Proverbs 25:28: "Whoever has no rule over his own spirit is like a city broken down, without walls." No specific Hebrew word in this sentence means "self-control," but "rule" certainly implies it. In its comments on this verse, the Interpreter's Dictionary of the Bible states:
The picture is that of a city whose walls have been so nearly destroyed as to be without defense against an enemy; so is the man who has no restraint over his spirit, the source of man's passionate energies. He has no defense against anger, lust, and the other unbridled emotions that destroy the personality. (vol. 4, p. 267)
Proverbs 16:32 shows a more positive side of self-control: "He who is slow to anger is better than the mighty, and he who rules his spirit than he who takes a city." Here Solomon uses an entirely different word for "rule," but the sense of self-control remains. A comparison of the two proverbs reveals the great importance of self-control as both an offensive and defensive attribute.
