16For if you give a blessing with the spirit, how will the man who has no knowledge say, So be it, after your prayer, seeing that he has not taken in what you are saying?
17For your giving of the blessing is certainly well done, but of no profit to the man without knowledge.
18I give praise to God that I am able to make use of tongues more than you all:
19But in the church it would be better for me to make use of five words of which the sense was clear, so that others might have profit, than ten thousand words in a strange tongue.
20My brothers, do not be children in mind: in evil be as little children, but in mind be of full growth.
21In 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.
22For 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.
