There is a series of transformations in Isaiah 60:17 that almost certainly contain allegories of spiritual transformation...

Bronze to Gold = Judgment transformed to righteousness.
Iron to Silver = Punishment transformed to redemption.
Wood to Bronze = Corruptible flesh transformed to/by judgment.
Stones to Iron = Legalism or injustice transformed to/by discipline.
Wood to Bronze to Gold = Flesh transformed thru judgment into righteousness.
Stones to Iron to Silver = Injustice transformed through correction into redemption.

At the Greater Exodus there will be peace in Jerusalem at last. No more Hamas, oppression, or hatred. #yeshua will be Israel's protector and sincere worship will be the key to safety.
Isaiah 60:18
