Shocho is a variant form of the place-name Socoh. It is one of several spellings used for that name in the biblical and Authorized Version traditions.
Shocho appears in 2 Chronicles 28:18, where it is identified with Shochoh in 1 Samuel 17:1 and Shoco in 2 Chronicles 11:7.
The supplied material treats Shocho as a variation in the spelling of Socoh rather than as a separately described place.
