1 Kings 14:4 - Joseph Benson’s Commentary on the Old and New Testaments

But Ahijah could not see He not only lived obscure and neglected in Shiloh, but was blind through age: yet he was still blessed with the visions of the Almighty; which require not bodily eyes; but are rather favoured by the want of them, the eyes of the mind being then most intent and least diverted. His eyes were set, &c. Hebrew, קמו משׁיבו, kamu misheibo, stood for his hoariness No longer performed their office, by reason of his great age. Perhaps the fibres and muscles by which the eyes and eye-lids are moved, were contracted and withered, the optic nerves become effete, or film or cataract was grown over his eyes.
