'Truthful' in the Bible

You must be truthful, honest and upright when you take an oath saying, 'As surely as the Lord lives!' If you do, the nations will pray to be as blessed by him as you are and will make him the object of their boasting."

The Lord said, "Go up and down through the streets of Jerusalem. Look around and see for yourselves. Search through its public squares. See if any of you can find a single person who deals honestly and tries to be truthful. If you can, then I will not punish this city.
