1 Samuel 22:3

Mizpeh of Moab Mentioned here only. Perhaps either the strong rock citadel afterwards known as Kir-Moab, now Kerakis meant: or some place not in Moab proper, but on the mountains of Abarim or Pisgah north of the Arnon, which would be more easily accessible from Bethlehem by way of Jericho. The long purple wall of the mountains of Moab is a striking feature in the view from Bethlehem (Sin. and Pal. p. 104), and would naturally suggest a retreat thither: but no doubt it was his connexion with Moab through his great-grandmother Ruth, which chiefly induced David to choose that country as a refuge for his parents.
