Vayyadbequ Pelishtim (=The Philistines pursued and caught up to). This is equivalent to vayyadbiqu. Similarly, vayyadrekhu et leshonam (=they bent their tongues; Jer 9:2) is equivalent to vayyadrikhu.

And they carried off his head and his armor … and they impaled his head in the temple of Dagon. But in the book of Samuel [it says], “and they impaled his body on the wall of Beth-shan” (1 Sam 31:10)! What is omitted there is filled in here; for they impaled his head in the temple of Dagon and his and his sons’ bodies on the wall of Beth-shan, and the people of Jabesh-gilead then took his and his sons’ bodies. They did not, however, take his head from the temple of Dagon. The reason the people of Jabesh-gilead took care of him is that they remembered what he did for them: he saved them when Nahash the Ammonite threatened them (1 Sam 11:1–11).

And [the people of Jabesh-gilead] fasted for seven days. This was in remembrance of the seven-day respite granted to them by Nahash the Ammonite (1 Sam 11:3), because it was during that time that they had been saved by Saul.

For not having fulfilled the command of (devar) the Lord. This refers to the matter of (devar) Amalek (1 Sam 15:8–9).

And did not seek the advice of the Lord. But in the book of Samuel it says, “And Saul inquired of the Lord, but the Lord did not answer him” (1 Sam 28:6), and that he sought the advice of the ghost only subsequently! Because he did subsequently seek the advice of the ghost, it was considered as if he had not sought the advice of the Lord—for he equated one inquiry with the other. Even though the Lord did not answer him, he should have reached out to the Lord again and repented fully before Him, rather than compounding his sinful behavior with the transgression of seeking the advice of the ghost.
