Zi'or (Heb. Tsior', צַיעֹר, smallness; Sept. Σιώρ v.r. Σωραίθ; Vulg. Sior), a town in the highland district of Judah (Jos 15:54), where it is mentioned in the group around Hebron to the south. SEE JUDAH, TRIBE OF. Eusebius and Jerome (Onomast. s.v.. Σιώρ) call it a village between Jerusalem and Eleutheropolis. It probably corresponds to the small village still called Sair on the road about six miles north-east of Hebron towards Tekoa (Robinson, Bibl. Res. 1, 488), traditionally pointed out as the site of the grave of Esau (Schwarz, Palest. p. 106).
