1 Chronicles 13:9

The threshingfloor of Chidon . For Chidon, the parallel place has Nachon ; possibly these are two names of the same place, or one form is a corruption of the ether; but there is nothing to determine for us which. Owing to the meaning of Nachon being "prepared," the version of Aquila is "to the prepared threshingfloor," with which the Jonathan Targum agrees, and (for this Chronicles passage) the Joseph Targum gives אֲתַר מְתַקַּן . The threshing- floor was a circular plot of hard ground, from fifty to one hundred feet in diameter, on which the oxen trampled out the grain. Threshingfloors evidently often became landmarks, and helped to designate places ( Genesis 50:10 ; 2 Samuel 24:16 ). The oxen stumbled . In the parallel place the Authorized Version renders "shook it." The Hebrew verb is the same ( שָׁמַט ) in both places. Its elementary meanings are "to strike" and "to throw down." Perhaps the meaning is near the Vulgate rendering, calcitrabant , and equivalent to the rendering, became restive.
