1 Corinthians 14:23-28

23Therefore if the whole church gathers together and all the people speak in tongues, and 1outsiders or unbelievers enter, will they not say that 2you are insane? 24But if all 3prophesy, and an unbeliever or an 4outsider 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, 10brothers and sisters? When you assemble, 11each one has a 12psalm, has a 13teaching, has a 14revelation, has a 15tongue, has an 16interpretation. 17All things are to be done for edification. 27If anyone speaks in a 18tongue, it must be by two or at the most three, and each one in turn, and one is to 19interpret; 28but if there is no interpreter, he is to keep silent in church; and have him speak to himself and to God.
