Proverbs 17:12 Let a bear robbed of her whelps meet a man, rather than a fool in his folly.
13 Whoso rewardeth evil for good, evil shall not depart from his house.
14 The beginning of strife is as when one letteth out water: therefore leave off contention, before it be meddled with.
This scripture starts off by telling us it would be better for us to meet a mother bear who has lost her cubs than to come into contact with a fool in his folly. A fool in his folly is not going to stop from trying to get people to turn to his way life.
As we continue, being thankful to someone doing evil is a certain way to make sure they will be more likely to do good. Also this tells us that we reap what we sew which means evil will not be a part of your household. Finally we see that water is used as an example to show how things can manifest. If a dam has a small link if it is not stop early it will eventually cause the dam to break. When anger or strife starts we should be quick to get it under control so it does not destroy you or a friend. Just like it hard to stop a dam from from breaking it is impossible to take bake a cross word said. Let us try to always be positive in what say even if we know someone is doing wrong. Let us be close enough to God that He gives us just what to say.
