Proverbs 17:11-13

¹¹Because wicked people are always trying to cause trouble, someone will be sent to severely punish them.

¹²A mother bear whose cubs have been taken away from her is dangerous, but it is more dangerous to confront a foolish person who is doing something foolish.

¹³If someone does something evil in return for something good being done to him, evil/trouble will never leave that person's family.
