The War Scroll

The War Scroll is part of the Dead Sea Scrolls and mostly describes the battle between the Sons of Light and the Sons of Darkness. You can read it here. Most of it consists of mundane details of battle order but there were some interesting parts. I was initially curious to read it because of some commonalities with Ephesians:

The first attack of the Sons of Light shall be undertaken against the forces of the Sons of Darkness, the army of Belial...
- War Scroll Col 1:1

For you were once darkness, but are now light in the Lord. Walk as children of light,
- Ephesians 5:8

wherein aforetime ye walked according to the course of this world, according to the prince of the power of the air, of the spirit that now worketh in the sons of disobedience;
- Ephesians 2:2

Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience.
- Ephesians 5:6

Also, notice the passage below echoes the Ephesians verses as well:

...You yourself made Belial for the pit, an angel of malevolence, his [dominio]n is in darkne[ss] and his counsel is to condemn and convict. All the spirits of his lot -- the angels of destruction-- walk in accord with the rule of darkness, for it is their only [des]ire...
- War Scroll Col 13:10-12

Belial is another name for Satan and his angels are described as angels of destruction. I talk about that in my post on Satan as well. In that post, I also talk about Satan's function of testing. See the passages below regarding testing:

...Throughout all our generations You have made Your mercies wondrous for the rem[nant of the people] during the dominion of Belial. With all the mysteries of his hatred they have not led us astray from Your covenant. His spirits of destruction You have driven [away from us. And when the me]n of his dominion [condemned themselves]...
- War Scroll Col 14:9-10

When [Belial] prepares himself to assist the Sons of Darkness, and the slain among the infantry begin to fall by God's mysteries and to test by these mysteries all those appointed for battle,
- War Scroll Col 16:11

Also, compare the passage below with Eph. 5:11:

...For they are a wicked congregation, all their deeds are in darkness;
- War Scroll Col 15:9

Do not participate in the unfruitful deeds of darkness, but rather expose them.
- Ephesians 5:11

This battle is described as a "Day of Vengeance" like I talk about in my Ephesians post on The Day of Destruction.

...All of them shall be volunteers for battle, pure of spirit and flesh, and prepared for the day of vengeance...
- War Scroll Col 7:5

Ultimately, I don't think Paul was alluding to The War Scroll when he wrote Ephesians but they do seem to share a common vernacular.
