'Border' in the Bible

The cows went straight on the way on the road to Beth Shemesh, on the one main road, {lowing as they went}. They did not turn aside to the right or to the left, and the rulers of [the] Philistines [were] walking after them up to the border of Beth Shemesh.

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.
