(Heb. Yazunm', יָנוּם , slumber, otherwise for יָנוּן, propagation; Septuag. Ι᾿ανούμ v. r. Ι᾿εμαϊ v ν, Vulg. Janun), a town in the mountains of Judah, mentioned between Eshean and Beth-tappuah (Joshua 15:53). The Heb. text has יָניּם (das s if anim', יָנַים ) by a manifest error, which is corrected in the Masoretic marg.; many copies have Yanus', יָנוּס, flight, as in the Eng. margin ‘ Janus." The Syriac version has Yalum. Eusebius (Onomast. s.v. Ι᾿ανουά ) mentions a place, Janua, three miles south of Legio, but admits that it cannot be the locality in question. M. de Saulcy (Nar. 1, 437) thinks the site may possibly be marked by the ruins of Jenheh, at the foot of a hill nearly south of Hebron; but, according to Dr. Robinson, the remains are little more than those of caves (Bib. Res. 2, 472). The associated names appear to indicate a district immediately northwest of Hebron (Keil. Comment on Joshua ad loc). The position corresponds with that of a ruined site, Ras Jabreh, marked on the first edition of Van de Velde's map immediately on' the west of the road directly north from Hebron to Jerusalem, and adjoining Khurbet enl-Nasara; but the second edition of the map omits both these sites, though the latter is explicitly mentioned in the Memoir (p. 247) as "a ruined village" visited by him as well as by Dr. Robinson (Researches, 1, 317).
