(Proverbs 21:29 KJV) A wicked man hardeneth his face: but as for the upright, he directeth his way.
I started off today thinking the focus of this verse was on the verbs. You could make a case from the English for a vital difference in the actions taken. That does not come through so well in the Hebrew. Both verbs are positive actions. The first has to do with being strong, the second with discernment.
The real focus is on the focus. The “wicked” (7563) is concerned with appearances. The “upright” (3477) is concerned with the actions. One is concerned with looking good, the other with doing good. We should be aware of those goals and realize that God looks at the heart. He is not confused by smoke and mirrors.
So? Walk upright. Walk straight. Do the right thing. People are watching and so is God. He will not be fooled, or mocked.
