Cuthah: One of the Babylonian cities or districts from which Shalmaneser
transplanted certain colonists to Samaria
(2 Kings 17:24) Some have
conjectured that the "Cutheans" were identical with the "Cossaeans"
who inhabited the hill-country to the north of the river Choaspes.
Cuthah is now identified with Tell Ibrahim, 15 miles north-east of
Babylon.
