Spirit of deep sleep as a weapon of warfare

Isaiah 29 vs 10

For the Lord hath poured out upon you the spirit of deep sleep, and hath closed your eyes: the prophets and your rulers, the seers hath he covered.

1. One of the Spirit that comes out from the presence of God is the Spirit of deep sleep.
2. When God pours out the Spirit of deep sleep, even monitoring eyes are closed permanently.
3. When God pours out the Spirit of deep sleep, the enemies become unaware of your progress.
4. The Spirit of deep sleep is one weapon of warfare God uses to neutralize the enemies of His people.
