Acts 2:8

every man in our own tongue i.e. language. There is no description here of any jargon or incoherent speech, we are told of utterances tested by the ears of those who had spoken these languages from their youth. The only question on which from St Luke's description we are left in uncertainty is this: whether the disciples did or did not understand the new words which they were enabled to utter. The only other place in the New Testament which throws any light on this matter is St Paul's first Epistle to the Corinthians. For a consideration of the expressions which St Paul there employs concerning these marvellous gifts, see note after Acts 2:13.
