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.
Textus Receptus (TR) - 1 Corinthians 14:22 >Ὥστε αἱ γλῶσσαι εἰς σημεῖόν εἰσιν, οὐ τοῖς πιστεύουσιν, ἀλλὰ τοῖς ἀπίστοις· ἡ δὲ προφητεία, οὐ τοῖς ἀπίστοις, ἀλλὰ τοῖς πιστεύουσιν.
