Albert Barnes Commentary Judges 4:11

"Now Heber the Kenite had separated himself from the Kenites, even from the children of Hobab the brother-in-law of Moses, and had pitched his tent as far as the oak in Zaanannim, which is by Kedesh." — Judges 4:11 (ASV)

Read, Heber the Kenite had severed himself from the Kenites who were of the children of Hobab, etc., unto the oak (or terebinth tree) in Zaanaim (or Bitzaanaim, which Conder identifies with Bessum, twelve miles southeast of Tabor, and near Kedesh on the Sea of Galilee).

This migration of Heber the Kenite, with a portion of his tribe, from the south of Judah to the north of Naphtali, perhaps caused by Philistine oppression, had clearly taken place recently. It is mentioned here to account for the subsequent narrative, but possibly also because the news of the great muster of the Israelites at Kedesh had been carried to Sisera by some of the tribe (Judges 4:12), whose tents we are here informed were in the immediate neighborhood of Kedesh.
