And behold, the angel of the Lord came upon him
Suddenly and at once, and stood by him; this was one of the ministering spirits sent forth by Christ, to minister to a servant of his:
and a light shined in the prison;
the Syriac version renders it, "in the whole house"; and the word that is used does signify an habitation, or a dwelling house properly, but is used also by the Greek writers F6 for a prison: this was an uncommon light produced by the angel, partly as an emblem of the presence, majesty, and power of God, who was present, to work a great deliverance; and partly for the use of Peter, that when being awaked he might see to rise and walk by:
and he smote Peter on the side, and raised him
he touched him on that side which lay uppermost, or punched him on it, in order to awake him, and raise him out of his sleep:
saying arise up quickly;
without delay, make haste:
and his chains fell off from his hands;
from both his hands, and were left with the soldiers, between whom he slept; which must be ascribed to an almighty power, which caused them to drop off.
