1 Corinthians 14
21 Ref In the law it is said, By men of other tongues and by strange lips will my words come to this people; and not even so will they give ear to me, says the Lord.
22 Ref For this reason tongues are for a sign, not to those who have faith, but to those who have not: but the prophet's word is for those who have faith, and not for the rest who have not.
23 Ref If, then, the church has come together, and all are using tongues, and there come in men without knowledge or faith, will they not say that you are unbalanced?
