“And David arose, etc.] From the place where he was: and he passed over; the borders of land of Canaan: with the six hundred men that [were] with him; having neither lost any, nor had any added to him, since he was at Keilah, (<092313>1 Samuel 23:13); unto Achish, the son of Maoch, king of Gath; whether this was the same Achish David was with before, (<092110>1 Samuel 21:10-13), is not certain; it seems as if he was not the same, since he is described as the son of Maoch, as if it was to distinguish him from him; though it is not improbable that he was the same person.
