בכא , 2 Samuel 5:23-24; 1 Chronicles 14:14-15; Psalms 84:7 . The LXX, in Chronicles, render the word by απιων , "pear trees;" so Aquila and the Vulgate, both in Samuel and Chronicles, "purorum." Others translate it the "mulberry tree:" More probably it is the large shrub which the Arabs still call "baca;" and which gave name to the valley where it abounded. Of this valley Celsius remarks, that it was "rugged and embarrassed with bushes and stones, which could not be passed through without labour and tears;" referring to Psalms 84:7; and the "rough valley," Deuteronomy 21:4; and he quotes from a manuscript of Abu'l Fideli a description of the tree which grew there, and mentions it as bearing a fruit of an acrid taste.
