Acts 12:8-10

Amplified Bible

⁸ The angel said to him, “Prepare yourself and strap on your sandals [to get ready for whatever may happen].” And he did so. Then the angel told him, “Put on your robe and follow me.” ⁹ And Peter went out following the angel. He did not realize that what was being done by the angel was real, but thought he was seeing a vision. ¹⁰ When they had passed the first guard and the second, they came to the iron gate that leads into the city. Of its own accord it swung open for them; and they went out and went along one street, and at once the angel left him.
