What does Isaiah 1:30 mean?
Isaiah has promised from the Lord that those who forsake Him will be consumed and destroyed (Isaiah 1:28). He has included those who worshipped false gods in groves of sacred oak trees and gardens with rituals that may have included sexual immorality. They worshipped false gods in hopes of being made stronger and perhaps more fertile (Isaiah 1:29). .These unfaithful Israelites will be embarrassed when the Lord's judgment falls. Instead of being stronger, they will end up like withered versions of these oaks and dried up gardens that are set aflame by the smallest spark (Isaiah 1:31). What's depicted here is not a typical autumn where leaves naturally fall. This is a wasting, shriveling experience for the oak, symbolic of intense suffering.
