🔼The name Maareh-geba in the Bible
It's not clear whether Maareh-geba is actually supposed to be a Biblical name or not. If it is, it occurs only in Judges 20:33, where the men of Israel ambush those of Benjamin at Maareh-geba, in retaliation of the atrocities committed by Benjaminites in Gibeah (Judges 20:33).
The ASV, NAS and JSP all have the Israelite ambush Benjamin in Maareh-geba; the NIV speaks of the "west of Gibeah"; the KJV, Darby and Young versions speak of "meadows of Gibeah" and Jay P. Green's literal translation has "plains of Gibeah".
🔼Etymology of the name Maareh-geba
The name Maareh-geba obviously consists of two elements. The first part comes from the noun מערה (ma'ara), meaning a bare or exposed place, from the root עור ('wr III):
The second part is the same as one of the various spellings of the name Gibeah. It comes from the noun גבעה (gib'a), meaning hill, which derives off the root גבע, meaning to be convex, projecting or high:
The name Maareh-geba would thus most literally mean Plateau Of Gibeah.
