Now the Hebrews who were with the Philistines as before, and who went up with them into the camp, [from the country] round about, even they also [turned] to be with the Israelites who were with Saul and Jonathan.
God caused the Philistines to fight one another (1 Samuel 14:20; cf. Judges 7:22; 2 Chronicles 20:23). Some Israelite deserters or mercenaries who were fighting for the Philistines even changed their allegiance and took sides with Jonathan. The tide of battle had turned. Beth-aven stood near Michmash, but the exact site is uncertain.
