kleft, klif, klift: The first of these words, from cleave, "to split," is a crevice or narrow opening, as "of the ragged rocks" (Isa 2:21); "under the clefts of the rocks" (Isa 57:5). "Clift" is an obsolete form of cleft, found in the King James Version Ex 33:22; Isa 57:5, but not in the Revised Version (British and American). "Cliff," an abrupt, precipitous, towering rock, is not in the Revised Version (British and American), but is found in the King James Version 2Ch 20:16, the Revised Version (British and American) "ascent," Job 30:6.
