Judges 1:34-36

34And the Amorites forced the children of Dan into the mountains, for they would not allow them to come down to the valley;

35and the Amorites were determined to dwell in Mount Heres, in Aijalon, and in Shaalbim; yet when the strength of the house of Joseph became greater, they were put under tribute.

36Now the boundary of the Amorites was from the Ascent of Akrabbim, from Sela, and upward.
