1 Corinthians 14:23-28

23Therefore if the whole church assembles together and all speak in tongues, and 1ungifted men or unbelievers enter, will they not say that 2you are mad? 24But if all 3prophesy, and an unbeliever or an 4ungifted man enters, he is 5convicted by all, he is called to account by all; 256the secrets of his heart are disclosed; and so he will 7fall on his face and worship God, 8declaring that God is certainly among you.

269What is the outcome then, 10brethren? When you assemble, 11each one has a 12psalm, has a 13teaching, has a 14revelation, has a 15tongue, has an 16interpretation. Let 17all things be done for edification. 27If anyone speaks in a 18tongue, it should be by two or at the most three, and each in turn, and one must 19interpret; 28but if there is no interpreter, he must keep silent in the church; and let him speak to himself and to God.
