'Palm trees' in the Bible

Now the descendants of the Kenite, Moses' father-in-law, went up with the people of Judah from the City of Date Palm Trees to Arad in the desert of Judah, located in the Negev. They went and lived with the people of Judah.

Eglon formed alliances with the Ammonites and Amalekites. He came and defeated Israel, and they seized the City of Date Palm Trees.
