1 Corinthians 14:16

14:16 Otherwise, if you are praising God with your spirit, how can someone without the gift say “Amen” to your thanksgiving, since he does not know what you are saying?

1 Corinthians 14:23-24

14:23 So if the whole church comes together and all speak in tongues, and unbelievers or uninformed people enter, will they not say that you have lost your minds? 14:24 But if all prophesy, and an unbeliever or uninformed person enters, he will be convicted by all, he will be called to account by all.

tn Grk “how can someone who fills the place of the unlearned say ‘Amen.’”
