Aceldama

the name which the Jews gave in their proper tongue, i.e., in Aramaic, to the field which was purchased with the money which had been given to the betrayer of our Lord. The word means "field of blood." It was previously called "the potter's field" (Matt 27:7; 27:8; Acts 1:19), and was appropriated as the burial-place for strangers. It lies on a narrow level terrace on the south face of the valley of Hinnom. Its modern name is Hak ed-damm.
