Concise Bible Dictionary:
Place where the Jews were in captivity, but from whence they would be brought to possess “the cities of the south” (Obad. 1:20). The LXX has “as far as Ephratha;” and the Vulgate “in Bosphoro.” Jerome considered the word signified “boundary,” and referred to the dispersion of the Jews in any region.
