(Proverbs 18:4 KJV) The words of a man's mouth are as deep waters, and the wellspring of wisdom as a flowing brook.
People speak. People write. I have often found myself in a situation where I know every word used but don’t have a clue to what is being said. New ideas are sometimes like that but so is nonsense. Solomon is telling us we need to look beyond the surface. “Deep” (6013) “waters” (4325) can signify either intensive thought or careful concealment.
In any case it can be dangerous to take what people say at face value. Okay, if someone says “I want my coffee black” you can probably accept that. If they say, “I was only trying to help” you might want to step back, see if you still have your wallet and lock up the silver.
So? Consider character when someone speaks to you. Do a little thinking and ask yourself if this person has been up-front with you or has always had excuses. Of course that means we should be honest too.
