1 Corinthians 14:26-28

Young's Literal Translation

²⁶ What then is it, brethren? whenever ye may come together, each of you hath a psalm, hath a teaching, hath a tongue, hath a revelation, hath an interpretation? let all things be for building up;

²⁷ if an [unknown] tongue any one do speak, by two, or at the most, by three, and in turn, and let one interpret;

²⁸ and if there may be no interpreter, let him be silent in an assembly, and to himself let him speak, and to God.
