G2399–ἰδιώτης–idiōtēs

As they looked on Peter and John so fearlessly outspoken--and also discovered that they were illiterate persons, untrained in the schools--they were surprised; and now they recognized them as having been with Jesus.

ἰδιῶται, idiōtai “ordinary,”

Otherwise, if you bless God in spirit only, how shall he who is in the position of an ungifted man say the `Amen' to your giving of thanks, when he does not know what your words mean?

ἰδιώτου idiōtou “uninstructed”

Accordingly if the whole Church has assembled and all are speaking in `tongues,' and there come in ungifted men, or unbelievers, will they not say that you are all mad?

ἰδιῶται idiōtai “uninstructed ones”

ἰδιώτης idiōtēs “unpolished”
