Bethmerhak

Beth-mer'hak (Heb. Beyth ham-Merchak', בֵּית הִמֶּרחָק house of the remoteness; Sept. translates οϊvκος ὁ μακράν, Vulg. procul a domo; A. V. "a place that was far off"), apparently the proper name of a locality near Jerusalem, and not far beyond the brook Kidron, where King David first halted in his exit from the city on the rebellion of Absalom (2Sa 15:17); doubtless a designation of the environs outside the city wall, in the valley of Jehoshaphat, as being the extreme limit of the houses.
