(Proverbs 16:10 KJV) A divine sentence is in the lips of the king: his mouth transgresseth not in judgment.
I think the literal note on this verse is an important insight. The NASB talks about an “err” (4603) by a king, or in our case, a president or other leader. The KJV comes closer by calling it a transgression. The marginal reading says it literally means, “be unfaithful.”
There is an element of deliberate decision involved here. It is not just a case of a leader being condemned for a mistake in judgement. It is not even a case of sin. It is the abandonment of duty and responsibility. It is a betrayal.
How do leaders betray their trust? The context talks about dishonest measures, lies, pride and wickedness. These apply to our leaders even more than they do to us. In a republic we have a responsibility to look at the character of our leaders. That applies from President to union stewards.
So? Expect a high standard. If the person does not measure up, don’t make excuses, make changes if possible. Keep your eyes open.
