Goad
Easton's Bible Dictionary (1897)
(Heb. malmad, only in Judg. 3: 31), an instrument used by ploughmen for guiding their oxen. Shamgar slew six hundred Philistines with an ox-goad. “The goad is a formidable weapon. It is sometimes ten feet long, and has a sharp point. We could now see that the feat of Shamgar was not so very wonderful as some have been accustomed to think.” In 1 Sam. 13:21, a different Hebrew word is used, dorban, meaning something pointed. The expression (Acts 9:5, omitted in the R.V.), “It is hard for thee to kick against the pricks”, i.e., against the goad, was proverbial for unavailing resistance to superior power.
Smith's Bible Dictionary (1863)
(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.
