Acts 12:9 Meaning and Commentary

Acts 12:9

And he went out and followed him
He came out from between the two soldiers, and out of that apartment in the prison, in which he was, and followed the angel where he led him:

and wist not that it was true that was done by the angel;
not that he thought the angel was a mere apparition, and all this that was done was a delusion; but he did not know whether this was matter of fact, or whether it was, not represented to him in a visionary way, as what could be, or would be done:

but thought he saw a vision;
imagined he was in a dream or a trance, and only saw these things in a vision, and that they were not really done, the whole was so amazing and astonishing.

Acts 12:9 In-Context

7 Suddenly an angel of the Lord appeared and a light shone in the cell. He tapped Peter on the side and woke him, saying, "Get up quickly." And the chains fell off his wrists.
8 The angel said to him, "Fasten your belt and put on your sandals." He did so. Then he said to him, "Wrap your cloak around you and follow me."
9 Peter went out and followed him; he did not realize that what was happening with the angel's help was real; he thought he was seeing a vision.
10 After they had passed the first and the second guard, they came before the iron gate leading into the city. It opened for them of its own accord, and they went outside and walked along a lane, when suddenly the angel left him.
11 Then Peter came to himself and said, "Now I am sure that the Lord has sent his angel and rescued me from the hands of Herod and from all that the Jewish people were expecting."
