Acts 4 King James Version
And as they spake unto the people, the priests, and the captain of the temple, and the Sadducees, came upon them,

The captain of the temple - See the Matthew 26:47; Luke 22:4 note. This was the commander of the guard stationed chiefly in the tower Antonia, especially during the great feasts; and it was his duty to preserve order and prevent any tumult. He came at this time to prevent a tumult or suppress a riot, as it was sup posed that the teaching of the apostles and the crowd collected by the healing of the lame man would lead to a tumult.
