NACON, THE THRESHING FLOOR OF
na'-kon, (nakhon; the King James Version Nachon): The place where Uzzah was smitten for putting forth his hand to steady the ark, hence, called afterward "Perezuzzah" (2 Samuel 6:8); in the parallel passage (1 Chronicles 13:9) we have kidhon, and in Josephus (Ant., VII, iv, 2) Cheidon. In 1 Samuel 23:23 the word nakhon occurs, and is translated "of a certainty," margin "with the certainty" or "to a set place"; also in 1 Samuel 26:4 it is translated "of a certainty," margin "to a set place." It is uncertain whether in 1 Samuel 6:6 it is a place-name at all; and no successful attempt has been made to identify either Nacon or Chidon; possibly they are both personal names.
