The word so rendered, ( 2 Samuel 12:31 ; 1 Chronicles 20:3 ) is probably a threshing-machine. The verb rendered "to harrow," ( Job 39:10 ; Isaiah 28:24 ; Hosea 10:11 ) expresses apparently the breaking of the clods, and is so far analogous to our harrowing --but whether done by any such machine as we call a "harrow" is very doubtful.
