Hidden, or hollow, a town east of Jordan (Num. 32:35), built by
the children of Gad. This word should probably be joined with
the word preceding it in this passage, Atroth-Shophan, as in the
Revised Version.
Smith's Dictionary
(bareness), one of the fortified towns on the east of Jordan which were taken possession of and rebuilt by the tribe of Gad. (Numbers 32:35)
