'Division' in the Bible

The {raiders} went out from the camp of [the] Philistines [in] three divisions. One division turned on the road to Ophrah toward the land of Shual.

One division turned on the road to Beth Horon, and one turned on the road toward the border overlooking the valley of Zeboim toward the wilderness.

So Saul returned from pursuing David, and he went to confront [the] Philistines. Therefore, they called that place the Rock of Division.
