UBS Dictionary of the Greek New Testament
verb | ἀπατάω
1 This series of meanings containing the stem ἀπατ overlaps considerably in meaning with the previous series containing the stem πλαν (31.8-31.11). Both sets of terms involve deception and erroneous views. It is difficult to determine the precise implications of differences in meaning, but it may be that terms with the stem πλαν are somewhat more related to general deceptive behavior rather than primarily to misconceptions.
