Proverbs 12:5

A good man does not plot evil plans. His plans respect God. The good man tries to help other people by his plans.

For example, someone might open a shop that sells food. If the shopkeeper is a good person, then he wants to sell good food at a fair price. But an evil shopkeeper might want to sell poor food at an expensive price.

The second part of this verse is about advice. You cannot trust an evil man’s advice. When he is advising you, he is plotting an evil plan. You do not know his plan. An evil man will not give sound advice. His advice is a lie. He wants to cheat you.
