(Heb. Mose-rah', מוֹסֵרָה , prob. i.q. מאֹסֵר , a Band [but the טךנאל הךס not local, as it has the tone; it is apparently fem.]; Sept. Μοσερά v.r. Μισαδαϊ v), the thirty-ninth station of the Israelites in the desert, between Jaakan and Gudgodah ( Deuteronomy 10:6); evidently at the foot of Mount Hor, since Aaron is said to have died there (comp.  Numbers 33:37-38). The name appears in the plur. form MOSEROTH, as an earlier station of the Israelites, in the inverse order ( Numbers 33:30-31). (See Exode). It may probably be identified with the small fountain Et-Tayibeh, at the bottom of the pass er-Rubay, leading to the western ascent of Mount Hor (Robinson's Researches, 2:583). This spring in the wady is quite choked with sand, but there is fine water in the ravines higher up the hill- side, where the Bedouin pitch their tents. Schwarz is entirely astray in locating it (Palest. page 213) at Wady El-Muzeiriah, in the heart of the western desert (Robinson, 1:277). Burckhardt vaguely suggested Wady Musa, or the valley of Petra; but this has no probability. Rowlands, in Fairbairn's Dictionary, contends at length for Jebel Madurah, nearly in the middle of the desert plateau; but in this he is evidently influenced by his theory of the location of Kadesh.
