Proverbs 26:11-13

¹¹Like a dog going back to the food which he has not been able to keep down, is the foolish man doing his foolish acts over again.

¹²Have you seen a man who seems to himself to be wise? There is more hope for the foolish than for him.

¹³The hater of work says, There is a lion in the way; a lion is in the streets.
