Joshua 19:42

Shaalabbin. Called Shaalbim in Judges 1:35. Perhaps the modern Selbit, a town of central Palestine, between Jerusalem and Lydda. The place was, for a time, held by the Amorites, who would not permit the Danites to occupy it. Later the Hebrews took it (1 Kings 4:9).

Ajalon. A city, probably in the Valley of Aijalon, which the Amorites refused to yield. The valley runs from Jerusalem toward the Mediterranean, cutting across the hills of the Shephelah toward Lydda.
