Easton's 1897 Bible Dictionary:

Sceptre
   (Heb. shebet = Gr. skeptron), properly a staff or rod. As a
   symbol of authority, the use of the sceptre originated in the
   idea that the ruler was as a shepherd of his people (Gen. 49:10;
   Num. 24:17; Ps. 45:6; Isa. 14:5). There is no example on record
   of a sceptre having ever been actually handled by a Jewish king.
