The name is derived, according to some, from Eber (Genesis 10:24), the ancestor of Abraham. The Hebrews are "sons of Eber" (Genesis 10:21).
Others trace the name of a Hebrew root-word signifying "to pass over," and hence regard it as meaning "the man who passed over," viz., the Euphrates; or to the Hebrew word meaning "the region" or "country beyond," viz., the land of Chaldea. This latter view is preferred. It is the more probable origin of the designation given to Abraham coming among the Canaanites as a man from beyond the Euphrates (Genesis 14:13).
A third derivation of the word has been suggested, viz., that it is from the Hebrew word 'abhar, "to pass over," whence 'ebher, in the sense of a "sojourner" or "passer through" as distinct from a "settler" in the land, and thus applies to the condition of Abraham (Hebrews 11:13).
