Thankful for studying Spiritual Warfare. Noticed Ephesians 6:11-13 has Hebrew poetic repitition:
A) Use all the armor and weaponry that God provides,
B) so that you will be able to stand
C) against the deceptive tactics of the Adversary.
C') For we are not struggling against human beings, but against the rulers, authorities and cosmic powers governing this darkness, against the spiritual forces of evil in the heavenly realm.
A') So take up every piece of war equipment God provides;
B') so that when the evil day comes, you will be able to resist; and when the battle is won, you will still be standing.
Thankful Roman soldiers used a "tortoise" formation to stand/move together in battle.
