References for 1 Corinthians 14:22
So if the whole church comes together and everyone speaks in tongues, and inquirers or unbelievers come in, will they not say that you are out of your mind?
References for 1 Corinthians 14:23
But if an unbeliever or an inquirer comes in while everyone is prophesying, they are convicted of sin and are brought under judgment by all,
as the secrets of their hearts are laid bare. So they will fall down and worship God, exclaiming, “God is really among you!”
References for 1 Corinthians 14:25
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

Two or three prophets should speak, and the others should weigh carefully what is said.
References for 1 Corinthians 14:29

For you can all prophesy in turn so that everyone may be instructed and encouraged.
The spirits of prophets are subject to the control of prophets.
