1 Corinthians 14:29 ASV

²⁷  If any man speaketh in a tongue, 'let it be' by two, or at the most three, and 'that' in turn; and let one interpret:

²⁸  but if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.

²⁹  And let the prophets speak 'by' two or three, and let the others discern.

³⁰  But if a revelation be made to another sitting by, let the first keep silence.

³¹  For ye all can prophesy one by one, that all may learn, and all may be exhorted;
