Proverbs 8:5

Solomon uses special meanings for the words ‘simple’ and ‘foolish’.

The ‘fool’ is proud and lazy. He does not want to serve God. He hates wisdom. He prefers to do evil things. If you try to teach a fool, he will hate you. He will only learn if God changes him.

The ‘simple’ person does not know what is right or wrong. He has not learned to be wise. He chooses to do evil things, because ‘everybody does it’. But you can teach a simple person. A simple person can learn to be wise.
