(the watch-tower ), a place mentioned once only -- ( 1 Samuel 19:22 ) --apparently as lying on the route between Sauls residence, Gibeah, and Ramah (Ramathaim-zophim), that of Samuel. It was notorious for "the great well" (or rather cistern) which it contained. Assuming that Saul started from Gibeah (Tuleil el-Ful ), and that Neby Samwil is Ramah, then Bir Nebolla (the well of Neballa) just south of Beeroth, alleged by modern traveller to contain a large pit would be in a suitable position for the great well of Sechu.
