Clear
CLEAR, CLEARNESS. The KJV tr. six Heb. and three Gr. expressions with this term. In almost all of the cases the terms refer to three aspects of light: opaque, translucent, and transparent, for which there are no exact equivalents in Heb. or Gr. More exact renderings of the passages would be (RSV): “You will be free from my oath” (Gen 24:41); “like the very heaven for clearness” (Exod 24:10); “like clear heat in sunshine” (Isa 18:4); “fair as the moon, bright as the sun” Song of Solomon; “I will...darken the earth in broad daylight” (Amos 8:9). In the NT the term is used in 2 Corinthians 7:11, “You have proved yourselves guiltless,” and in Revelation 21:18, “The city was pure gold, clear as glass,” and 22:1, “the river of the water of life, bright as crystal.”

From this physical, it is applied, in a moral sense, to character, as spotless and free from guilt, or charge, or obligation "from oath" (Ge 24:8); "from transgression" (Ps 19:13). Hence, the verb "to clear" means juridically to declare or prove innocent, to vindicate (Ge 44:16; Ex 34:7; Nu 14:18; compare hagnos, 2Co 7:11, the Revised Version (British and American) "pure") "Be clear when thou judgest" (Ps 51:4) refers to the proof and vindication of the righteousness of God.
