for all the tall mountains, for all the high hills,
Why do you look with envy, O mountains with many peaks, at the mountain where God has decided to live? Indeed the Lord will live there permanently!
for every high tower, for every fortified wall,
On every high mountain and every high hill there will be streams flowing with water, at the time of great slaughter when the fortified towers collapse.
Every valley must be elevated, and every mountain and hill leveled. The rough terrain will become a level plain, the rugged landscape a wide valley.
and every arrogant obstacle that is raised up against the knowledge of God, and we take every thought captive to make it obey Christ.
