1 Samuel 30:14

Upon the south of the Cherethites— It is plain, from this relation, that the Cherethites were Philistines, see 1 Samuel 30:16 and that the Amalekites were enemies to the Philistines; and therefore, however David might have asked beside the intentions of his benefactor, yet he certainly did not act against his interest in destroying them. Calmet, in his dissertation upon the origin of the Philistines, says, that the name Cherethites, or Cherethians, is the same as Cretans; and he maintains that this people were Aborigines of Crete.
