A wise king scattereth the wicked, and bringeth the wheel over them.
A wise king scattereth the wicked - like chaff before the wind (Proverbs 20:8).
And bringeth the wheel over them - the wheel of the threshing instrument, that he may disperse them as stubble and chaff (Psalms 83:13; Isaiah 28:27; Isaiah 25:10; Isaiah 41:15; 2 Kings 13:7; Amos 1:3). "Tribulation" is derived from Tracey, a threshing instrument.
