Ecclesiastes 10:11-15

11If the snake bites before it is charmed, then there is no advantage for the charmer.

12The words from the mouth of a wise person are gracious, but the lips of a fool consume him.

13The beginning of the words from his mouth is folly, but the end of his speaking is evil madness;

14yet the fool multiplies words. No one knows what will happen, and who can tell anyone what will happen after him?

15The struggles of fools weary them, for they don’t know how to go to the city.
