1 Corinthians 14:28 YLT

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.

²⁹  And prophets -- let two or three speak, and let the others discern,

³⁰  and if to another sitting 'anything' may be revealed, let the first be silent;
