Contradiction
CONTRADICTION [isbe]
CONTRADICTION - kon-tra-dik'-shun: the King James Version for antilogia (Heb 7:7; 12:3). In the former passage, the Revised Version (British and American) has "without any dispute," i.e. what has been said requires no argument; in the latter "gainsaying" which is scarcely an improvement, the reference being to the oral attacks upon the words and character of Jesus.
