Rith'mah (Heb. Rithmah', רַתמָה, heath; Sept. ῾Ραθαμᾶ), the seventeenth station of the Hebrews in the wilderness (Nu 33:18-19). About half a day's journey south from Wady Kiseima, SEE AZMON is found a valley called Wady Rithimath, or Wady Abu-Retemat. Rothem literally is a broom bush; hence Rithmah, the region of the brush or heath, and near this wady the broom bushes are abundant. So Schwarz (Palest. p. 212), who identifies Rithmah with Kerdesh-Barnea. It probably lay immediately west of that place. SEE EXODE.
