Cleft

CLEFT. A. Noun. 1. סָעִיף, H6186, cleft, fissure; LXX σχισμή crack; Vul. caverna, cavern; Luther, Felsklippe, rocky ridge. Isaiah predicts that men will hide in the “clefts” of the cliffs (2:21; KJV the “tops” of the ragged rocks).

2. שָׁסַע, H9117, cleft; LXX ὀνυχίζον. In KJV “cleft” is also the “split” in the hoof of an animal (Deut 14:6).

B. Verb. פָּלַג, H7103, split, divide; LXX ἑτοιμάζω, G2286, prepare. Yahweh has “cleft” [“divided,” KJV] a channel for the torrents of rain (Job 38:25).

International Standard Bible Encyclopedia (1915)

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.
