Proverbs 22:12

​Be courageous enough to tell the truth (always), even to the point of embarrassment, God will see it, and settle the matter in your favor.

It's not just what we say, that can be dishonest or misleading,

but what we (withhold) and do not say, can be just as deceptive, so, work at being a champion at both 

"God guards knowledge with a passion, but he’ll have nothing to do with deception."
