And the Philistines gathered themselves together
 From different parts, and formed a considerable army: 
 and came and pitched in Shunem;
 a city, in the borders of the tribe of Issachar, of which (See Gill on Joshua 19:18); 
 and Saul gathered all Israel together, and they pitched in Gilboa;
 a range of mountains, near Jezreel, and which Jerom F2 calls the mountains of the Philistines, six miles from Scythopolis, where there is a large village called Gelbus.
