“He that is soon angry dealeth foolishly” (17).

What more is there to say?

Well, a few verses later God says more on the subject:

“He that is slow to wrath is of great understanding: but he that is hasty of spirit exalteth folly” (19).

Then we have two other verses (among plenty of others):

“He that is slow to anger is better than the mighty; and he that ruleth his spirit than he that taketh a city” (Proverbs 16:32).

“Be not hasty in thy spirit to be angry: for anger resteth in the bosom of fools” (Ecclesiastes 7:9).

So, how do I go about ruling my spirit and slowing my anger?

“Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things” (Philippians 4:8).

That is hard to do!

But it can be done.

And must be done. Self-control and properly-focused thinking are not optional for the Christian.
