Ephesians 6:11

6:11 Clothe yourselves with the full armor of God so that you may be able to stand against the schemes of the devil.

Ephesians 6:13-20

6:13 For this reason, take up the full armor of God so that you may be able to stand your ground on the evil day, and having done everything, to stand. 6:14 Stand firm therefore, by fastening the belt of truth around your waist, by putting on the breastplate of righteousness, 6:15 by fitting your feet with the preparation that comes from the good news of peace, 6:16 and in all of this, by taking up the shield of faith with which you can extinguish all the flaming arrows of the evil one. 6:17 And take the helmet of salvation and the sword of the Spirit, which is the word of God. 6:18 With every prayer and petition, pray at all times in the Spirit, and to this end be alert, with all perseverance and requests for all the saints. 6:19 Pray for me also, that I may be given the message when I begin to speak – that I may confidently make known the mystery of the gospel, 6:20 for which I am an ambassador in chains. Pray that I may be able to speak boldly as I ought to speak.
