Watson's Biblical & Theological Dictionary 
a city belonging to the half tribe of Manasseh, on the west of Jordan, and not far from the river. It was a considerable city in the time of Eusebius and St. Jerom, and was then, as it had been for several ages before, called Scythopolis, or the city of the Scythians, from some remarkable occurrence when the Scythians made an irruption into Syria. It is said to be six hundred furlongs from Jerusalem, 2Ma_12:29 . After the battle of Mount Gilboa, the Philistines took the body of Saul, and hung it against the wall of Bethshan, 1 Samuel 31:10 . Bethshan is now called Bysan, and is described by Burckhardt as situated on rising ground on the west of the Ghor, or valley of Jordan.
