Easton's 1897 Bible Dictionary:

Tabret
   (Heb. toph), a timbrel (q.v.) or tambourine, generally played by
   women (Gen. 31:27; 1 Sam. 10:5; 18:6). In Job 17:6 the word
   (Heb. topheth) "tabret" should be, as in the Revised Version,
   "an open abhorring" (marg., "one in whose face they spit;" lit.,
   "a spitting in the face").
