'Understand' in the Bible

not to many peoples of unintelligible speech and difficult language, whose words you cannot understand -- surely if I had sent you to them, they would listen to you!

"Therefore, son of man, pack up your belongings as if for exile. During the day, while they are watching, pretend to go into exile. Go from where you live to another place. Perhaps they will understand, although they are a rebellious house.

Understand that it is not for your sake I am about to act, declares the sovereign Lord. Be ashamed and embarrassed by your behavior, O house of Israel.
