In the going up of Luhith. — Here again we have an echo from Isaiah 15:5. Jerome (Onomast. s.v. Luith) describes it as between Zoar and Areopolis (= Rabbath-Moab). The ascent was probably to a local sanctuary. A various reading, Laboth, followed by the LXX., gives the meaning “the ascent of planks,” as though it were a wooden staircase. Alike in that and in the descent from Horonaim (possibly the fugitives who came down from the heights of the one city are represented as going up with wailing to the other) the enemies of Moab would hear the cry that proclaimed its downfall.
