2 Chronicles 21:16 - Joseph Benson’s Commentary on the Old and New Testaments

The Lord stirred up against Jehoram the spirit of the Philistines A people who had been fully subdued and dispirited; but whose spirits and courage God now raised, that they might do his work. And of the Arabians, that were near the Ethiopians Hebrew, near the Cushites, that is, the Ethiopians properly so called, for they were parted only by the Red sea; or rather a people in Arabia, frequently mentioned in Scripture, and so called either for their likeness in colour and complexion to the Ethiopians, or because one of these tribes was a colony from the other.
