What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up.
References for 1 Corinthians 14:26
If anyone speaks in a tongue, two—or at the most three—should speak, one at a time, and someone must interpret.
If there is no interpreter, the speaker should keep quiet in the church and speak to himself and to God.
Two or three prophets should speak, and the others should weigh carefully what is said.
References for 1 Corinthians 14:29
And if a revelation comes to someone who is sitting down, the first speaker should stop.
