And he brought forth the people that were therein, and put them under saws, and under harrows of iron, and under axes of iron, and made them pass through the brickkiln: and thus did he unto all the cities of the children of Ammon. So David and all the people returned unto Jerusalem.
And he brought out the people that were in it, and cut them with saws, and with harrows of iron, and with axes. Even so dealt David with all the cities of the children of Ammon. And David and all the people returned to Jerusalem.
Matthew George Easton, 1897
(Heb. harits), a tribulum or sharp threshing sledge; a frame armed on the under side with rollers or sharp spikes (2 Sam. 12:31; 1 Chr. 20:3).
Heb. verb sadad, to harrow a field, break its clods (Job 39:10; Isa. 28:4; Hos. 10: 11). Its form is unknown. It may have resembled the instrument still in use in Egypt.
William Smith, 1884
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.
