Ephesians 6:12

9 And, you masters, do the same things to them, not making use of violent words: in the knowledge that their Master and yours is in heaven, and he has no respect for a man's position.

10 Lastly, be strong in the Lord, and in the strength of his power.

11 Take up God's instruments of war, so that you may be able to keep your position against all the deceits of the Evil One.

12 For our fight is not against flesh and blood, but against authorities and powers, against the world-rulers of this dark night, against the spirits of evil in the heavens.

13 For this reason take up all the arms of God, so that you may be able to be strong in the evil day, and, having done all, to keep your place.

14 Take your place, then, having your body clothed with the true word, and having put on the breastplate of righteousness;

15 Be ready with the good news of peace as shoes on your feet;
