si-mil'-i-tud: In the King James Version means either "an exact facsimile" (Ps 106:20 the King James Version, the Revised Version (British and American) "likeness"; Ro 5:14, etc.), or else "the form itself" (Nu 12:8; De 4:12,15,16 for temunah, "form" (so the Revised Version (British and American))); compare LIKENESS. the English Revised Version has retained the word in 2Ch 4:3; Da 10:16 (the American Standard Revised Version "likeness"), while the English Revised Version and the American Standard Revised Version have used "similitudes" in Ho 12:10 (damah, "be like"). The meaning is "I have inspired the prophets to speak parables."
