Blessing Valley of
Valley of Blessing, a translation of the name Valley of Berachah (benediction), which was borne by the valley in which Jehoshaphat celebrated the miraculous overthrow of the Moabites and Ammonites. It was from this circumstance it derived its name; and from the indications in the text, it must have been in the tribe of Judah, near the Dead Sea and Engedi, and in the neighborhood of Tekoa (2 Chronicles 20:23-26).
