17:21 "But Peter continued knocking: and when they had opened the door, and saw him, they were astonished. But he, beckoning unto them with the hand to hold their peace, declared unto them how the Lord had brought him out of the prison." And Peter "departed, and went into another place." Joy and praise filled the hearts of the believers, because God had heard and answered their prayers and had delivered Peter from the hands of Herod.
