Ephesians 6:18-20

18praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—

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

20for which I am an ambassador in chains; that in it I may speak boldly, as I ought to speak.
