(Proverbs 23:8 KJV) The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.
Most people have experienced food poisoning sometime in their lives. The reason it gets us is because it is often non-detectable. Whatever is making the food unacceptable is subtle but septic. You don’t know you have it until it is too late.
Solomon’s comment is figurative but based on the literal. There are people who seem to be so right and yet are so wrong. Often we don’t know it until life starts to go bad. With food poisoning I don’t know if we could refuse to vomit. I think that if we fought it the feeling would continue to get worse until we gave it up. I am not so sure we could resist until death. There are people who come into our lives that will continue to make us miserable until we get rid of them.
So? Is there a “friend” that needs to go away? Is there a relative that needs to be avoided? Solomon would say so.
