ranz (kilyah; nephros, words promiscuously translated "heart," "inward parts," "kidneys" or "reins." The latter word, which is derived from Latin "renes" through Old French "reins", has given place in modern English to the word "kidneys" (see Skeat, Concise Etymological Dictionary of the English Language, 398). the Revised Version (British and American) has, however, retained the older word, at least in the margin, in all passages in which it is found in the King James Version): According to Hebrew psychology the reins are the seat of the deepest emotions and affections of man, which God alone can fully know. Thus the Revised Version (British and American) has substituted "heart" for "reins" in the text of Job 19:27; Ps 7:9; 16:7; 26:2; 73:21; Pr 23:16; Jer 11:20; 12:2; 17:10; 20:12; the translation "inward parts" is found but once (Ps 139:13). In one passage the King James Version has translated the Hebrew [~halac ("loins") with "reins" (Isa 11:5), where the Revised Version (British and American) has rightly substituted "waist" (which see). The Greek word nephros (which is etymologically allied to the Middle English nere, Get. Niere; see Skeat, ibid, 231, under the word "Kidney") is found in 1 Macc 2:24; Re 2:23.
See KIDNEYS.
