Kommentar zu Divrej Hajamim I 10:17

And the Philistines fought with Israel He relates only Saul’s downfall; when relating the story of David, he does not tell of his disgrace, only of his heroism and greatness, because the Book pertains to him and to the kings of Judah.

and the archers discovered him Come and see that (Prov. 21:30): “... there is neither wisdom nor understanding, etc. against the Lord,” because man’s ways are before the Lord. Benjamin’s enemies would fall before them [when they used] the bow because they were well trained with the bow, as it is written: “[Ehud the son of Gera, the Benjamite,] a man with a shriveled right hand,” (Judges 3:15). And so it is written, concerning Jonathan (I Samuel 20:20): “And I shall shoot three arrows to the side, as though I shot at a mark.” And it is written below (I Chron. 12:2) concerning Benjamin: “Armed with bows, shooting with the right and left hands, etc.” and concerning Asa in this Book (II 14:7): “... and out of Benjamin, who bore shields and drew bows, etc.” But when the Lord turned away from Saul [who was from the tribe of Benjamin], he fell into the hands of the archers, into something that was his own craft. and he was terrified of the archers וַיָחֶל like (Esther 4:4): “...and the queen was extremely terrified (וַתִּתְחַלְחַל).”

and they fasted seven days Why did they imperil their lives more than the rest of Israel to remove the bodies of Saul and his sons from Mount Gilboa? Because Saul had done them a favor by saving them when Nahash the Ammonite marched upon them. [They fasted seven days] corresponding to the seven days that they [the Ammonites] gave them [to see] if a savior would come [to save] them, [at which time] they fasted seven days; perhaps a savior would come to them. Since Saul came and saved them, they fasted now too seven days, and also because of the mourning which was customary to observe seven days, because they were also their kinsmen, for when Israel slew the inhabitants of Gibeah in the incident of the concubine in Gibeah (at the end of Judges), the people of Jabesh Gilead gave their daughters to Benjamin, when they grabbed them from the dances.

And Saul died because of the treachery that he had committed He committed two treacherous acts by inquiring of the familiar spirit: one when he inquired after Samuel, and one when he inquired of familiar spirits, and in the Aggadah of Samuel (24:6) we learn that he committed five treacherous acts

concerning the word of the Lord that he did not keep that which Samuel had commanded him, as it is written (I Sam. 10:8): “Seven days shall you wait,” and because he dealt treacherously in the war of Amalek [by sparing Agag].
