'Honest' 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 says, "These people are like soldiers who have readied their bows. Their tongues are always ready to shoot out lies. They have become powerful in the land, but they have not done so by honest means. Indeed, they do one evil thing after another and do not pay attention to me.
