Oad

Smith's Bible Dictionary

Goad.  Judges 3:31;  1 Samuel 13:21. The Hebrew word, in the latter passage, probably means the point of the plough-share . The former word does probably refer to the goad, the long handle of which might be used as a formidable weapon. The instrument, as still used in countries of southern Europe and western Asia, consists of a rod about eight feet long, brought to a sharp point, and sometimes cased with iron at the head.
