And he went out, and followed him; and wist not that it was true which was done by the angel; but thought he saw a vision.

And he went out, and followed; and he knew not that it was true which was done by the angel, but thought he saw a vision.

And going out, he followed him, and he knew not that it was true which was done by the angel: but thought he saw a vision.

And 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.

And he went out, and followed; and he wist not that it was true which was done by the angel, but thought he saw a vision.

And he went out, and followed him, and knew not that it was true which was done by the angel; but thought he saw a vision.

and having gone forth, he was following him, and he knew not that it is true that which is done through the messenger, and was thinking he saw a vision,

So Peter went out, following him, yet could not believe that what the angel was doing was real, but supposed that he saw a vision.

And he went out after him; and he was not certain if what was done by the angel was a fact, for it seemed to him that he was seeing a vision.

And going out, he followed him. And he did not know this truth: that this was being done by an Angel. For he thought that he was seeing a vision.

Peter followed him out, not knowing that what was happening under the angel's guidance was real, but thinking that he was seeing a vision.

He knew not that it was true. He did not think that it was a vain or false visor, as Satan doth oftentimes delude men with jugglings; but true is taken in this place for that which is done naturally and after the manner of men. For we must note the contrariety [antithesis] that is between the thing itself and the vision. Furthermore, though he think that it is a vision, yet doth he willingly obey; whereby his obedience is proved, whilst that being content with the commandment of the angel alone, he doth not inquire nor reason what he must de, but doth that which he is commanded to do.

And wist not - Knew not.
That it was true - That it was real.
But thought he saw a vision - He supposed that it was a representation made to his mind similar to what he had seen before. Compare Acts 10:11-12. It was so astonishing, so unexpected, so wonderful, that he could not realize that it was true.

He - wist not - He knew not; from the Anglo-Saxon, to know. He supposed himself to be in a dream.

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.

wist not that it was true; but thought he saw a vision--So little did the apostle look for deliverance!

Thought he saw a vision. All seemed so strange that, just aroused from sleep, he was uncertain whether it was real.
The first and second ward. Watches. The soldiers on watch seem to have been stationed apart, one near Peter's door, the other near the gate.
The iron gate. The outer gate of the prison. It was after it was passed, and the angel had left him in the street, that Peter was first sure that it was no vision, but that the Lord had delivered him.
