Unknown Tongue (1Co 14:2,4,13-14,19,27) is a gloss of the A.V.; for the Greek has simply γλῶσσα, a tongue, obviously meaning a different living language from that ordinarily employed by the speaker (γλῶσσα ἑτέρα, Mr 16:17; Ac 2; Ac 4). Others understand an ecstatic utterance of abrupt, incoherent, and unintelligible expressions which needed an interpreter. See the monographs cited by Volbeding, Index Programmatum, p. 73.
