New American Standard Bible NAS
New International Version NIV
10 There are, perhaps, a great many kinds of languages in the world, and no kind is without meaning.
10
Undoubtedly there are all sorts of languages in the world, yet none of them is without meaning.
11 If then I do not know the meaning of the language, I will be to the one who speaks a barbarian, and the one who speaks will be a barbarian to me.
11
If then I do not grasp the meaning of what someone is saying, I am a foreigner to the speaker, and the speaker is a foreigner to me.
12 So also you, since you are zealous of spiritual gifts, seek to abound for the edification of the church.
12
So it is with you. Since you are eager for gifts of the Spirit, try to excel in those that build up the church.
13 Therefore let one who speaks in a tongue pray that he may interpret.
13
For this reason the one who speaks in a tongue should pray that they may interpret what they say.
14 For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
14
For if I pray in a tongue, my spirit prays, but my mind is unfruitful.
15 What is the outcome then? I will pray with the spirit and I will pray with the mind also; I will sing with the spirit and I will sing with the mind also.
15
So what shall I do? I will pray with my spirit, but I will also pray with my understanding; I will sing with my spirit, but I will also sing with my understanding.
16 Otherwise if you bless in the spirit only, how will the one who fills the place of the ungifted say the "Amen " at your giving of thanks, since he does not know what you are saying?
16
Otherwise when you are praising God in the Spirit, how can someone else, who is now put in the position of an inquirer, say “Amen” to your thanksgiving, since they do not know what you are saying?
17 For you are giving thanks well enough, but the other person is not edified.
17
You are giving thanks well enough, but no one else is edified.
18 I thank God, I speak in tongues more than you all;
18
I thank God that I speak in tongues more than all of you.
19 however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue.
19
But in the church I would rather speak five intelligible words to instruct others than ten thousand words in a tongue.
20 Brethren, do not be children in your thinking; yet in evil be infants, but in your thinking be mature.
20
Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults.
