“And after this it came to passe, that Dauid smote the Philistines, and subdued them: and Dauid tooke Metheg-Ammah out of the hand of the Philistines.”
1611 King James Version (KJV)
8:1 And David took - Gath and her towns, as it is expressed in the parallel place, #1Chron 18:1|. Which are called Metheg - ammah, or the bridle of Ammah, Gath was situate in the mountain of Ammah; and because this being the chief city of the Philistines, and having a king, which none of the rest had, was the bridle which had hitherto kept the Israelites in subjection.
