Beit She’an was mentioned as a city conquered in Joshua’s day. It was the place where Saul and Jonathan’s carcasses were hung in humility by the Philistines before the men of Jabesh-Gilead came by night and took them down and buried them.
Recent digs at Beit She’An have uncovered the ruins of a city from the Greek/Roman period. Although Beit She’An was uncovered down to this point, deeper into this site are ruins that go back as far as King Saul and earlier periods of biblical history.
Joshua 17:11–16—11And Manasseh had in Issachar and in Asher Bethshean and her towns, and Ibleam and her towns, and the inhabitants of Dor and her towns, and the inhabitants of Endor and her towns, and the inhabitants of Taanach and her towns, and the inhabitants of Megiddo and her towns, even three countries. 12Yet the children of Manasseh could not drive out the inhabitants of those cities; but the Canaanites would dwell in that land. 13Yet it came to pass, when the children of Israel were waxen strong, that they put the Canaanites to tribute; but did not utterly drive them out. 14And the children of Joseph spake unto Joshua, saying, Why hast thou given me but one lot and one portion to inherit, seeing I am a great people, forasmuch as the Lord hath blessed me hitherto? 15And Joshua answered them, If thou be a great people, then get thee up to the wood country, and cut down for thyself there in the land of the Perizzites and of the giants, if mount Ephraim be too narrow for thee. 16And the children of Joseph said, The hill is not enough for us: and all the Canaanites that dwell in the land of the valley have chariots of iron, both they who are of Bethshean and her towns, and they who are of the valley of Jezreel.
Judges 1:27—Neither did Manasseh drive out the inhabitants of Bethshean and her towns, nor Taanach and her towns, nor the inhabitants of Dor and her towns, nor the inhabitants of Ibleam and her towns, nor the inhabitants of Megiddo and her towns: but the Canaanites would dwell in that land.
1 Samuel 31:8–13—8And it came to pass on the morrow, when the Philistines came to strip the slain, that they found Saul and his three sons fallen in mount Gilboa. 9And they cut off his head, and stripped off his armour, and sent into the land of the Philistines round about, to publish it in the house of their idols, and among the people. 10And they put his armour in the house of Ashtaroth: and they fastened his body to the wall of Bethshan. 11And when the inhabitants of Jabeshgilead heard of that which the Philistines had done to Saul; 12All the valiant men arose, and went all night, and took the body of Saul and the bodies of his sons from the wall of Bethshan, and came to Jabesh, and burnt them there. 13And they took their bones, and buried them under a tree at Jabesh, and fasted seven days.
2 Samuel 21:12–14—12And David went and took the bones of Saul and the bones of Jonathan his son from the men of Jabeshgilead, which had stolen them from the street of Bethshan, where the Philistines had hanged them, when the Philistines had slain Saul in Gilboa: 13And he brought up from thence the bones of Saul and the bones of Jonathan his son; and they gathered the bones of them that were hanged. 14And the bones of Saul and Jonathan his son buried they in the country of Benjamin in Zelah, in the sepulchre of Kish his father: and they performed all that the king commanded. And after that God was intreated for the land.
