THE DICTIONARY — Easton’s Bible Dictionary (1897)
an architectural term found only in Ezekiel 40: 16, 21, 22, 26, 29. There is no absolute proof that the Israelites employed arches in their buildings. The arch was employed in the building of the pyramids of Egypt. The oldest existing arch is at Thebes, and bears the date B.C. 1350. There are also still found the remains of an arch, known as Robinson’s Arch, of the bridge connecting Zion and Moriah. (See TYROPOEON VAT LEY.)

arch ('ayil; Septuagint ta ailam, in sense of "posts" or "colonnade"): Referred to repeatedly in Eze 40:16 ff, but translation is an error for "porch" or "portico." the Revised Version (British and American) gives in marg, "or, colonnade. The meaning of the Hebrew word is uncertain." The principle of arch construction was known to the Jews and examples of early Jewish rude arches have been found in Palestine. An arched form need not necessarily be constructed with radiating joints; it can be corbelled as at Mycenae (Treasury of Atreus). This type of construction has been found also in Palestine.
