'Understand' in the Bible

You are not being sent to many peoples of unintelligible speech or difficult language, whose words you cannot understand. No doubt, if I sent you to them, they would listen to you.

“Son of man, get your bags ready for exile and go into exile in their sight during the day. You will go into exile from your place to another place while they watch; perhaps they will understand, though they are a rebellious house.
