to revile, to defame, to blaspheme, reviling to speak against someone in such a way as to harm or injure his or her reputation (occurring in relation to persons as well as to divine beings) One way in which βλασφημέω and βλασφημία[a] were used in speaking of defaming God was by claiming some kind of equality with God. Any such statement was regarded by the Jews of biblical times as being harmful and injurious to the nature of God.
