Watchman,
Pisteuw, according to Bauer, Arndt & Gingrich's Lexicon means, 'believe something ... be convinced of something' (1 Cor 13:7; 1 John 4:16), 'testimony was believed' (2 Thess 1:10) [1957:666].
There are many other examples of the use of the verb
pisteuw in BAG. None of them indicate what you want
pisteuw to mean.
You are relying too heavily on Vine's Dictionary when there is more extensive scholarship available.
Thayer gives some meanings of
pisteuw as:
- 'The thing believed being evident from the preceding context' (Matt 24:23 [26]; Mk 13:21; 1 Cor 9:18).
- Especially 'in a moral and religious reference, pisteuein [the infinitive] is used in the N. T. of the conviction and trust to which a man is impelled by a certain inner and higher prerogative and law of the soul ... absolutely to trust in Jesus or in God as able to aid either in obtaining or in doing something' (Matt 8:1321:22; Mk 5:36; 9:23....) [1887/1962:511].
To want to exclude the meaning of 'I believe' for
pisteuw goes beyond the information supported by the 2 major lexicons.
Do you want me to check out the meaning of
pisteuw in Kittel & Friedrich (eds) and Colin Brown (ed)? These are the 2 major word studies for students of the NT.
