Se'chu (Heb. with the art. has-Seku', .חַשּׂכוּ, the watch-tower, implying that the place was on or near an elevation; Sept. Σεχί v. r. Σεφεί), a region in Ramah, containing a famous well (or rather cistern, בּוֹר), which Saul passed while in pursuit of David (1Sa 19:22). "Assuming that Saul started from Gibeah (Tuleil el-Ful), and that Neby Samwil is Ramah [?], then Bir Neballa (the well of Neballa), alleged by a modern traveller (Schwarz, Palest. p. 127) to contain a large pit, would be in a suitable position for the great well of Sechu. Schwarz himself (p. 157) would identify it with Askar, on the south-east end of Mount Eba], and the well with Jacob's Well in the plain below; and Van de Velde (S. and P. ii, 53 sq.) hesitatingly places it at Shuk, in the mountains of Judah north-east of Hebron; but this they are forced into by their respective theories as to the position of Ramathaim-Zophim" (Smith). Sechu is perhaps represented by the present Khuraib er-Ram, which still contains a cistern (Robinson, Later Res. p. 287), and lies near er-Ram (Ramah) directly on the road from Tuleil el-Ful (Gibcah of Saul).
