Charles Ellicott Commentary Judges 20:45

"And they turned and fled toward the wilderness unto the rock of Rimmon: and they gleaned of them in the highways five thousand men, and followed hard after them unto Gidom, and smote of them two thousand men." — Judges 20:45 (ASV)

To the rock of Rimmon—i.e., of the pomegranate. As the tree is common in Palestine (Numbers 20:25; Deuteronomy 8:8; etc.), the name is naturally common.

There was one Rimmon in Zebulon (Joshua 19:13), another in Judah (Joshua 15:32), south of Jerusalem (Zechariah 14:10; Nehemiah 11:29).

This particular Rimmon is a steep, conical hill of white limestone (Robinson, 1:440), not far from Gibeah. It is located fifteen miles north of Jerusalem and six miles east of Bethel (“towards the sun-rising”). It is still called Rimmon.

They gleaned.—A metaphor from the vintage, like the phrase “trode down” from Judges 20:43. (See Jeremiah 6:9: “They shall glean the remnant of Israel as a vine.”)

To Gidom.—A place entirely unknown, and hence omitted in the Vulgate.
