16 A charioteer, also of Gaza, stricken by a demon in his chariot became perfectly stiff, so that he could neither move his hand nor bend his neck. He was brought on a litter, but could only signify his petition by moving his tongue; and was told that he could not be healed unless he first believed in Christ and promised to forsake his former occupation. He believed, he promised, and he was healed: and rejoiced more in the saving of the soul than in that of the body.
