The meaning of Arch in the Bible
(From Easton's Bible Dictionary)

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 BC 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 VALLEY .)
