1 Samuel 14:3-4

14:3 Now Ahijah was carrying an ephod. He was the son of Ahitub, who was the brother of Ichabod and a son of Phineas, son of Eli, the priest of the Lord in Shiloh. The army was unaware that Jonathan had left.

14:4 Now there was a steep cliff on each side of the pass through which Jonathan intended to go to reach the Philistine garrison. One cliff was named Bozez, the other Seneh.
