Deuteronomy 2:13

Now rise up Sam., LXX, And now rise and break camp; cp. Deuteronomy 2:24.

and get you over the brook Zered Wâdy, or torrent-valley, Zered. JE, Numbers 21:12, they marched thence, the E. desert of Mo'ab, and camped in the W. Zered. The name, LXX Zaret, does not occur again in the O.T. nor is it in Josephus. Euseb. and Jer. give it only as the name of a desert wâdy. On the Mâdabâ Mosaic map (5th century) a wâdy flowing to the Dead Sea, S. of Kerak, bears the letters -ΑΡΕΔ, according to some, but if this reading be correct it maybe no more than a conjecture. The theory that the Zered was the W. el-Ḥsa is impossible; as we have seen, Israel was already N. of that S. frontier of Mo'ab. Equally impossible is the view substituted for this by most commentaries, that it was an upper stretch of the W. Kerak; for Brünnow and Musil have shown that the W. Kerak runs up E. but a short distance from Kerak. N. of the W. el-Ḥsa the Hajj road crosses the W. es-Sulṭanî, the great S. affluent of the Môjeb or Arnon, and proper frontier between the fertile land of Mo'ab and the E. desert. The W. es-Sulṭanî forms a distinct landmark on this route, and, because of the water always to be found by digging in its bed, is a suitable camping-place. So Musil, Moab, 316, 319 n., 15. But if this be the Zered, Israel crossed it not, as Musil implies, from E. to W. for in that case they would have had to bend E. again to his probable site for -Ar at Medeyyneh (see Deuteronomy 2:9), or cross the difficult lower stretches of the Arnon but from S.W. to N.E. as the Hajj road does now.
