🔼The name Karkor in the Bible
The name Karkor occurs only once in the Bible. It's the name of the place where the Midianite kings Zebah and Zalmunna and their 10,000 remaining soldiers ended up after their army self-destructed due to the action of Gideon and his famous 300 men (Judges 8:10).
After Midian's decimation, Gideon quickly mustered army of men from Naphtali, Asher, Manasseh and Ephraim, and pursued Zebah and Zalmunna. When he caught them he ordered his young son Jether to kill them, but Jether declined and Gideon executed them himself.
🔼Etymology of the name Karkor
The name Karkor is identical (with a small difference in the much later added Masoretic vowel symbols) to the word קרקר (qarqar), which is used in Numbers 24:17 to describe the fate of the sons of Sheth: complete destruction.
To a Hebrew audience, the name Karkor would mean He Will Tear Down, but because Karkor was probably far to the east of the Jordan, scholars appear to prefer to relate this name to Arabic. Jones' Dictionary of Old Testament Proper Names doesn't directly offer an interpretation of this name but refers to an Arabic word that is also a doubling of a core-word. And that Arabic word means Soft And Level Ground. NOBSE Study Bible Name List appears to agree with Jones and reads Even Ground. BDB Theological Dictionary doesn't translate the name Karkor.
