The Lord showed him huge mounds of earth that resembled large anthills.
Creatures started coming out of the mounds in all directions.       
Every direction had a different looking creature.
Dave asked what these were.
The Lord said this is the first wave.
These are spirits of division sent out to destroy relationships: to divide families, churches, cities, and even nations.
The Lord told him to warn everyone to be on guard, and to protect their relationships from the enemy.

We have seen too many friends and family members become victims of these spirits of division.
Please heed this warning. 
The Bible says we are not ignorant of the devil's devices.
If we walk in love, forgiveness, and unity we can overcome the enemy.
Sometimes we may have to take the blame, Jesus did.
