Adummim

the red ones, a place apparently on the road between Jericho and Jerusalem, "on the south side of the torrent" Wady Kelt, looking toward Gilgal, mentioned (Josh 15:7 ; 18:17). It was nearly half-way between Jerusalem and Jericho, and now bears the name of Tal-at-ed-Dumm. It is supposed to have been the place referred to in the parable of the Good Samaritan (Luke 1:10 -37). Recently a new carriage-road has been completed, and carriages for the first time have come along this road from Jerusalem.
