2 Samuel 8:1

Metheg-ammah— Some learned men think this should be translated, Metheg, and her mother; i.e. the daughter and the mother city; Metheg, and Gath her metropolis: though others choose to translate these words, the bridle of the angle, apprehending that Gath was so called, on account of its being a garrison which kept all the contiguous country of Judea in awe. This is certain, that it was the metropolis of one of the five Philistine principalities, the seat of their kings, and the mother of giants.
