Easton's Bible Dictionary (1897)
Something hidden, a town of Benjamin (Ezra 2:27), east of Bethel and south of Migron, on the road to Jerusalem (Isa. 10:28). It lay on the line of march of an invading army from the north, on the north side of the steep and precipitous Wady es-Suweinit (“valley of the little thorn-tree” or “the acacia”), and now bears the name of Mukhmas. This wady is called “the passage of Michmash” (1 Sam. 13:23). Immediately facing Mukhmas, on the opposite side of the ravine, is the modern representative of Geba, and behind this again are Ramah and Gibeah.
This was the scene of a great battle fought between the army of Saul and the Philistines, who were utterly routed and pursued for some 16 miles towards Philistia as far as the valley of Aijalon. ” The power of Benjamin and its king now steadily increased. A new spirit and a new hope were now at work in Israel.
