The Kenites left the City of Palm Trees and went with the men of Judah. They went to the desert of Judah to live with the people there. This was in the Negev near the city Arad. (The Kenites were from the family of Moses’ father-in-law.)
He said to the Kenites, “Go away! Leave the Amalekites. Then I won’t destroy you with the Amalekites. You showed kindness to the Israelites when they came out of Egypt.” So the Kenites left the Amalekites.
