Ephesians 6:16-18

Young's Literal Translation

¹⁶ above all, having taken up the shield of the faith, in which ye shall be able all the fiery darts of the evil one to quench,

¹⁷ and the helmet of the salvation receive, and the sword of the Spirit, which is the saying of God,

¹⁸ through all prayer and supplication praying at all times in the Spirit, and in regard to this same, watching in all perseverance and supplication for all the saints --
