'Hypocrite' in the Bible

With his mouth a hypocrite destroyeth his neighbour; but through knowledge are the righteous delivered.

Therefore the Lord will not rejoice in their young men, neither will he have mercy on their fatherless and on their widows; for every one is a hypocrite and an evildoer, and every mouth speaketh folly. For all this his anger is not turned away, and his hand is stretched out still.
