Chi'don (Hebrews Kidon´, כַּירֹן a dart; Sept. Χειδών, but some omit), the name which in 1Ch 13:9 is given to the threshing-floor at which the accident to the ark, on its transport from Kirjath-jearim to Jerusalem, took place, and the death of Uzzah; on this account it was afterwards known as PEREZ-UZZAH. In the parallel account in 2 Samuel 6, the name is given as NACHON SEE NACHON (q.v.), which is nearly equivalent in sense. Whether there were really two distinct names for the same spot, or whether the one is simply a corruption or alteration of the other, is quite uncertain (see Gesenius, Thesaur. p. 683; Simonis, Onom. p. 339-40). Josephus (Ant. 7:4, 2) has "Chidon" (Χειδών). Some have even ventured to identify the spot with the threshing-floor of Ornan the Jebusite, on Mount Moriah. The Jewish tradition (Jerome, Quaest. Heb. on 1Ch 11:9) was that Chidon acquired its name from being the spot on which Joshua stood when he stretched out the weapon of that name (A. V. "spear") towards Ai (Jos 8:18). But this is irreconcilable with all our ideas of the topography of the locality, which was evidently not far N.W. of Jerusalem, possibly at the present ruins Khurbet el-Bistun (Van de Velde's Map).
