What does 2 Kings 18:32 mean?

until I come and take you away to a land like your own—a land full of grain and new wine, bread and vineyards, olive trees and honey. You’ll live, not die. Don’t listen to Hezekiah when he tells you, ‘The Lord will save us.’ 2 Kings 18:32 - Modern Text Bible

(He promises a good life in exile, trying to make surrender sound better than trusting God and staying put.)
