Acts 12:7-9

⁷And lo, an angel of the Lord came there, and a light shone in the prison: and having smitten the side of Peter, he roused him up, saying, Rise up quickly. And his chains fell off his hands.

⁸And the angel said to him, Gird thyself, and bind on thy sandals. And he did so. And he says to him, Cast thine upper garment about thee and follow me.

⁹And going forth he followed him and did not know that what was happening by means of the angel was real, but supposed he saw a vision.
