Charles Ellicott Commentary Joshua 19:14

"and the border turned about it on the north to Hannathon; and the goings out thereof were at the valley of Iphtah-el;" — Joshua 19:14 (ASV)

Hannathon (Kefr-’Andn, sheet 9) is the northeast corner of the boundary. The valley (ravine) of Jiphthah-el (God’s opening) seems to be the gorge running south-west from the north of Hannathon towards the plain.
