(Proverbs 14:15 KJV) The simple believeth every word: but the prudent man looketh well to his going.
Notice the different words chosen by the KJV, “simple” (6612a) and the NASB, “naive”. The modern choice is much more gentle. It is also less to the point. Naive can mean someone who is simply not experienced enough to recognize danger when it rears it head. Simple says you can’t learn. It is almost the same difference as between ignorant and stupid. I wonder how it was understood in 1611. It is not a trait that should be associated with God’s people.
As I look at the different translations on my software I see other choices: Stupid, innocent, foolish, fool, unthinking person, and thoughtless. The root word means wide open and spacious.
So? We are to be focused. We are to understand priorities and moral imperatives. We are to be obedient servants of a Holy God.
