1 Chronicles 10:1

Now the Philistines fought against Israel; and the men of Israel fled from before the Philistines, and fell down slain in mount Gilboa.

The Philistines fought against Israel and drove its army into flight. The men of Israel fled from before them and fell down slain in great numbers on Mount Gilboa. This defeat is bound up with the death of Saul, and the chapter in which it stands records that death and gives the reason for his reverses.
