1 Corinthians 14:28-30

Amplified Bible

²⁸ But if there is no one to interpret, the one [who wishes to speak in a tongue] must keep silent in church; let him speak to himself and to God. ²⁹ Let two or three prophets speak [as inspired by the Holy Spirit], while the rest pay attention and weigh carefully what is said. ³⁰ But if an inspired revelation is made to another who is seated, then the first one must be silent.
