Calah Chalach
Archimandrite Nikifor’s Biblical Encyclopedia
(fullness of days, maturity, or strength) (Gen 10:11-12) - one of the cities built in Assyria by Asshur, or more probably Nimrod, between the Tigris and upper Euphrates. Xenophon called it Larissa and mentioned an ancient pyramidal monument there. Under Layard's direction, major excavations yielded Assyrian antiquities for the British Museum, including royal statues, the pagan god Nebo, obelisks, and a lioness. Cuneiform inscriptions showed that its Assyrian name closely resembled the Hebrew Calah.
Some commentators identified Calah with Kalah Shergat and Nimrud with Resen and Larissa; the source argues instead from Genesis 10:12 and the distances that Nimrud more plausibly represents Calah.
