Ephesians 6:18-20

praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; 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, for which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.
