Isaiah 17:4 speaks of a time of judgment for Israel, symbolizing the loss of its former strength and prosperity. The “glory of Jacob” will be diminished, and the nation’s abundance (“fatness of his flesh”) will fade, leading to a period of hardship and weakness. This serves as a warning of the consequences of Israel’s disobedience, reflecting the broader theme of God’s judgment on nations that stray from His covenant. The verse emphasizes the transient nature of worldly prosperity and the importance of remaining faithful to God.
