Ephesians 6:18

¹⁶ Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.

¹⁷ And take the helmet of salvation, and the sword of the Spirit, which is the word of God:

Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;

¹⁹ And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel,

²⁰ For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.

Do read the surrounding verses too, because the context often says more than a single verse.
