1 Corinthians 14:21-22
(21) In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord.
(22) Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.
14:21-22. This summary argument in verses 21-25 began with the citation of a portion of Isaiah’s prophecy against Israel (Isa. 28:11-12). Because Israel refused to listen to God’s message proclaimed by His prophets, Isaiah predicted that another message would come. This one would be delivered in a foreign tongue unintelligible to the Israelites, yet unambiguous (cf. 2 Kings 17:23). The foreign tongue symbolized God’s rejection (cf. Deut. 28:49; Isa. 33:19), His disciplinary response to Israel’s stiff-necked rebellion against Him (cf. 2 Kings 17:14; Acts 7:51). Foreigners instead of Israel became the temporary servants of God (cf. Isa. 5:26; Hab. 1:6; Matt. 21:43; Rom. 10:19-21), and their foreign tongue was a punitive sign to Israel of what had taken place.
That seems to be the significance which Paul attached to tongues. As such, the primary arena for its exercise was not the company of believers but . . . unbelievers (cf. Matt. 13:10-15, on parables). Uninterpreted tongues had their place but not in the church where prophecy benefited believers (1 Cor. 14:3).
