Heap of witness, the name of the pile of stones erected by Jacob and Laban to mark the league of friendship into which they entered with each other (Gen. 31:47, 48). This was the name given to the “heap” by Jacob. It is Hebrew, while the name Jegar-sahadutha, given to it by Laban, is Aramaic (Chaldee or Syriac). Probably Nahor’s family originally spoke Aramaic, and Abraham and his descendants learned Hebrew, a kindred dialect, in the land of Canaan.
