The text is Ephesians 6:10-17, the famous “armor of God” passage, from the World English Bible.

10Finally, be strong in the Lord, and in the strength of his might.
11Put on the whole armor of God, that you may be able to stand against the wiles of the devil.
12For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places.
13Therefore put on the whole armor of God, that you may be able to withstand in the evil day, and, having done all, to stand.
14Stand therefore, having the utility belt of truth buckled around your waist, and having put on the breastplate of righteousness,
15and having fitted your feet with the preparation of the Good News of peace;
16above all, taking up the shield of faith, with which you will be able to quench all the fiery darts of the evil one.
17And take the helmet of salvation, and the sword of the Spirit, which is the word of God;

I should make one note about the text here; the World English Bible renders a portion of verse 12 as follows: “…against the world’s rulers of the darkness of this age”. I omitted the word “world’s” because the text reader stumbled over it and the meaning of the text isn’t significantly changed by its omission. This is also identical to the wording of some versions, such as the New King James Bible.
