Targum zu Kohelet 9:14

14. The body of a man is compared to a little city and heroes, a few soldiers are in its midst and are slight in its merit in the heart of man helpful to the body [against] the evil inclination which may be compared to a great and powerful king enters the body to conquer and it surrounds the heart in order to make it err and it builds against it a dwelling place because it wishes to cause him to depart from the way which is straight before the Lord to capture him in the great snares of Gehenna in order to burn him seven times for his sins.
