'Horsemen' in the Bible

Then he summoned two of the centurions and said, "Make ready two hundred soldiers to go to Caesarea along with seventy horsemen and two hundred spearmen by nine o'clock tonight,

The next day they let the horsemen go on with him, and they returned to the barracks.

When the horsemen came to Caesarea and delivered the letter to the governor, they also presented Paul to him.
