Ze'dad (Heb. Tsedasd', צַדָד [with. ה directive, Tseda'dah, צדָדָה, slope; Sept. Σαδαδάκ v.r. Σαραδάκ, etc.), one of the landmarks on the north border of the land of Israel, as promised by Moses (Nu 34:8) and as restored by Ezekiel (Eze 47:15). In the former passage it occurs between "the entrance of Hamath" and Ziphron, and in the latter between the "road to Hethlon" and Hamath. A place named Siudud exists to the east of the northern extremity of the chain of Antilibanus, about fifty miles E.N.E. of Baalbek and thirty five S.S.E. of Hums (Robinson, Bibl. Res. 2. 507: Wetzstein, Reis. üb. Hauran, p. 88), which Porter thinks is identical with Zedad (Five Years in Damascus, 2, 354356; Giant Cities of Bashan, p. 317); and so also apparently rabbi Schwarz (Palest. p. 26); but the boundaries of Palestine proper never extended so far northward. SEE TRIBE. A trace of the name possibly lingers in the desert plain called Sahil Judeideh, on the western slope of Antilibanus, in or in ear the district of Zebedany (Robinson, Later Bibl. Res. p. 490).
