1 Corinthians 1:22 King James Version (KJV)

²² For the Jews require a sign, and the Greeks seek after wisdom:

1 Corinthians 13:8 King James Version (KJV)

⁸ Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.

1 Corinthians 14:21-22 King James Version (KJV)

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.
