Ecclesiastes 10:13-15

¹³The beginning of the words of his mouth is foolishness; and the end of his talk is mischievous madness.

¹⁴A fool also multiplies words. Man doesn’t know what will be; and that which will be after him, who can tell him?

¹⁵The labor of fools wearies every one of them; for he doesn’t know how to go to the city.
