Salecah (  Deuteronomy 3:10 ,   Joshua 13:11;   Joshua 12:5 ,   1 Chronicles 5:11 ) was the most easterly of the towns claimed by Israel. It was assigned to the tribe of Gad, and is always described as being on the eastern frontier of Bashan. But it is better Indicated less theoretically as being in the extreme south-east of the Hauran. On account of its commanding position it has always been of strategic importance; but it was probably never permanently occupied by any of the Israelitish people. It was a Nahatæan and Roman stronghold, and a station on the great trade and military road from Gadara and Edrel eastward through the desert to the Persian Gulf. It is now inhabited by Druses, and bears the name Salkhad .
