GEDEROTHAIM (gĕ-de*chrŏthā'ĭm, two walls or two sheep pens). Another name for Gederah (Josh.15.36).
GEDEROTHAIM gĭ dĭr’ ə thā’ ĭm (גְּדֵרֹתָ֑יִם, two sheep pens). Last of fourteen names in Joshua 15:33-36 (see Gederah). However, the LXX treats “Gederothaim” as a noun and translates it as “[Gederah] and her sheep pens” (Gr. καί αἱ ἐπαύλεις αὐτη̂ς). This requires emending the last “m” of Gederothaim to “h.” The MT contains fourteen names without Gederothaim, but the differences between the MT and the LXX list could raise questions about other names also. The identification of the site, and even if it is a genuine place name, remains uncertain.
International Standard Bible Encyclopedia (1915)
Stands as the 15th in a list which professes to give only the names of 14 cities in the Judean Shephelah (Jos 15:36). the margin suggests that we might read "or" for "and" after Gederah, but this is impossible. Septuagint reads, "and its cattle shelters." Probably, however, the name has arisen by dittography from the preceding GEDERAH (which see).
