Vs 9: If a wise man contends with a foolish man, whether the fool rages or laughs, there is no peace.
This is so true. Don't you often have discussions or arguments in your mind with certain people? They always listen to reason - in your mind - There are some people you can't reason with, thus no peace. The answer, don't bother getting into a discussion or debate with people like this, it'll just lead to arguments.
Vs 11: A fool vents all his feelings, but a wise man holds them back.
I wonder if Solomon was being diplomatic here by saying 'fool' instead of 'woman'? Only joking, only joking! We don't vent like that!! But really, this is a challenge for me - TO KEEP QUIET - but I shall persevere. I don't want to be thought of as a fool.
Vs 23: A man's pride will bring him low, but the humble in spirit will retain honour.
If we remain humble though, God's word says He will elevate you. Sadly, in the world the humble are looked down on and the prideful are icons. As Christians, we shouldn't be too bothered by this as we should desire to please God and not man.
Proverbs speaks often of humility. It is how God wants us to live our lives. My encouragement to you is to strive to remain humble in all things, because to please God is more to be desired than to please man.
