trans - fôrm ´ ( Romans 12:2; the Revised Version (British and American) 2 Corinthians 3:18 for μεταμορφόομαι , metamorphóomai , and the King James Version 2 Corinthians 11:13 , 2 Corinthians 11:14 , 2 Corinthians 11:15 for μεταασχηματίζω , metaschēmatı́zō , the Revised Version (British and American) "fashion"): The commentaries often explain the former word as connoting a change of nature, while the latter refers only to the appearance, but this distinction is probably fanciful.
