Migron
Migron is a place in the territory of Benjamin, named in two passages set centuries apart. In Saul's time it marks the resting-place of Israel's king on the eve of Jonathan's raid; in Isaiah's prophecy it is one stop on an enemy army's march toward Jerusalem.
Saul's camp
In the campaign against the Philistines, Saul's reduced force halts at the edge of his home town. "And Saul remained in the uttermost part of Gibeah under the pomegranate-tree which is in Migron: and the people who were with him were about six hundred men" (1 Sa 14:2). Migron is fixed by a single pomegranate-tree on the outskirts of Gibeah, the perimeter where Saul keeps his shrunken army while Jonathan goes forward alone.
The advance from the north
Centuries later the same place reappears as a waypoint in an oracle of invasion. "He has come to Aiath, he has passed through Migron; at Michmash he lays up his baggage" (Isa 10:28). The line tracks an army's southward push through the Benjaminite plateau toward Jerusalem; Migron is the second stage, between Aiath and the supply-depot at Michmash.
