A — 1: γλῶσσα
(Strong's #1100 — Noun Feminine — glossa — gloce'-sah )

is used of (1) the "tongues ... like as of fire" which appeared at Pentecost; (2) "the tongue," as an organ of speech, e.g., Mark 7:33; Romans 3:13; 14:11; 1—Corinthians 14:9; Philippians 2:11; James 1:26; 3:5,6,8; 1—Peter 3:10; 1—John 3:18; Revelation 16:10; (3) (a) "a language," coupled with phule, "a tribe," laos, "a people," ethnos, "a nation," seven times in the Apocalypse, Revelation 5:9; 7:9; 10:11; 11:9; 13:7; 14:6; 17:15; (b) "the supernatural gift of speaking in another language without its having been learnt;" in Acts 2:4-13 the circumstances are recorded from the viewpoint of the hearers; to those in whose language the utterances were made it appeared as a supernatural phenomenon; to others, the stammering of drunkards; what was uttered was not addressed primarily to the audience but consisted in recounting "the mighty works of God;" cp. Acts 2:46; in 1Cor., chapters 12 and 14, the use of the gift of "tongues" is mentioned as exercised in the gatherings of local churches; 1—Corinthians 12:10 speaks of the gift in general terms, and couples with it that of "the interpretation of tongues;" chapt. 14 gives instruction concerning the use of the gift, the paramount object being the edification of the church; unless the "tongue" was interpreted the speaker would speak "not unto men, but unto God," 1—Corinthians 14:2; he would edify himself alone, 1—Corinthians 14:4 , unless he interpreted, 1—Corinthians 14:5 , in which case his interpretation would be of the same value as the superior gift of prophesying, as he would edify the church, 1—Corinthians 14:4-6; he must pray that he may interpret, 1—Corinthians 14:13; if there were no interpreter, he must keep silence, 1—Corinthians 14:28 , for all things were to be done "unto edifying," 1—Corinthians 14:26 . "If I come ... speaking with tongues, what shall I profit you," says the Apostle (expressing the great object in all oral ministry), "unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching?" (1—Corinthians 14:6 ). "Tongues" were for a sign, not to believers, but to unbelievers, 1—Corinthians 14:22 , and especially to unbelieving Jews (see 1—Corinthians 14:21 ): cp. the passages in the Acts.
