'Folly' in the Bible

Therefore the Lord will not rejoice over their young men, neither will he have compassion on their fatherless and widows; for everyone is profane and an evildoer, and every mouth speaks folly. For all this his anger is not turned away, but his hand is stretched out still.

For the fool will speak folly, and his heart will work iniquity, to practice profanity, and to utter error against Yahweh, To make empty the soul of the hungry, and to cause the drink of the thirsty to fail.
