וַיָּק֜וּמוּ כָּל־אִ֣ישׁ חַיִל֮ וַיֵּלְכ֣וּ כָל־הַלַּיְלָה֒ וַיִּקְח֞וּ אֶת־גְּוִיַּ֣ת שָׁא֗וּל וְאֵת֙ גְּוִיֹּ֣ת בָּנָ֔יו מֵחוֹמַ֖ת בֵּ֣ית שָׁ֑ן וַיָּבֹ֣אוּ יָבֵ֔שָׁה וַיִּשְׂרְפ֥וּ אֹתָ֖ם שָֽׁם׃
Da machten sich alle tapfern Männer auf und gingen die ganze Nacht und nahmen den Leichnam Sauls und die Leichname seiner Söhne von der Mauer von Bet-San und kamen mit ihnen nach Jabes zurück und verbrannten sie daselbst.
Radak
על הפגרים, the carcasses which are whole. This term is not applied to the animals which had been cut in half as part of the sacrificial procedures, [presumably, the author does not feel comfortable in the Torah describing sacrifices which had been accepted by G’d winding up as the food for vultures. Ed.] The author quotes a number of examples where the word פגר occurs in the Bible, in all of which the reference is to a whole carcass, not to a section of it. (compare Isaiah 14,19; Chronicles I 10,12; Samuel I 31,12) The symbolism in all this is that there would hardly be a generation in which the gentile nations would not attempt to devour the Jewish people, and to annihilate them utterly. Nonetheless, in the final analysis, G’d has always saved us from becoming total victims. This confirms the prediction in Leviticus 26,44 that even during our darkest days when we are being punished collectively for our sins and the sins of our fathers, “I will not despise you and allow you to be wiped out completely.” In the verse following the one we just quoted, the Torah adds verbatim: וזכרתי להם ברית ראשונים, at such a time “I will remember for them the covenant I concluded with the forefathers.”
