Admah
Easton's Dictionary
Earth, one of the five cities of the vale of Siddim (Gen. 10:19). It was destroyed along with Sodom and Gomorrah (19:24; Deut. 29:23). It is supposed by some to be the same as the Adam of Josh. 3:16, the name of which still lingers in Damieh, the ford of Jordan. (See ZEBOIM.)
Smith's Dictionary
International Standard Bible Encyclopedia
ad'-ma ('adhmah): From a root signifying red; one of the Cities of the Plain (Ciccar) (Ge 10:19; 14:2,8; De 29:23; Ho 11:8) upon which Abraham and Lot looked from the heights of Bethel; destroyed with Sodom and Gomorrah. Conder tentatively identifies it with the City of Adam referred to in Jos 3:16, and thinks that perhaps the name may be preserved in that of Damieh Ford, near the mouth of the river Jabbok; but that point could not have been in view from Bethel.
