1 Corintios 14

Por lo tanto, las lenguas son una señal, no a los creyentes, sino a los incrédulos. Mas la profecía es por señal, no para incrédulos, sino para creyentes.

Así que, las lenguas por señal son, no á los fieles, sino á los infieles: mas la profecía, no á los infieles, sino á los fieles.

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.

Therefore other languages are for a sign, not to those who believe, but to the unbelieving; but prophesying is for a sign, not to the unbelieving, but to those who believe.
