1 Samuel 13:7

Hebrews went over. When Saul sounded the call to arms, he said, “Let the Hebrews hear” (v. 3). Yet v. 7 notes that “the Hebrews'' fled across Jordan (the words “some of’ not being in the original text), while v. 6 states that Israel hid in the caves “in the hill country of Ephraim” (ch. 14:22, RSV). The word “Hebrews” is used consistently by the Philistines in referring to their opponents, but the author of Samuel seems to differentiate between the two terms, “Israel” and “Hebrews,” as, for example, in v. 19, where mention is made of the fact that the Philistines controlled all the workers in iron, “lest the Hebrews make them swords.” In contrast, the author himself says that “the Israelites went down to the Philistines” to have their implements sharpened. The LXX, however, here translates the word “Hebrews” as “slaves.” See on v. 3.
