1 Corinthians 14:26-28

MNT(i) 26 What follows, then, brothers? Whenever you meet together, each contributes something; a psalm, a sermon, a revelation, a tongue, an interpretation. Let all be done for edification. 27 If any one speaks in an unknown tongue, let it be by two, or at the most by three, and that in turn, and let some one interpret. 28 But if there is no one to interpret, let them keep silence in the church, and speak to themselves and to God.
