2 Corinthians 12:5-7

Revised Standard Version

⁵ On behalf of this man I will boast, but on my own behalf I will not boast, except of my weaknesses. ⁶ Though if I wish to boast, I shall not be a fool, for I shall be speaking the truth. But I refrain from it, so that no one may think more of me than he sees in me or hears from me. ⁷ And to keep me from being too elated by the abundance of revelations, a thorn was given me in the flesh, a messenger of Satan, to harass me, to keep me from being too elated.
