1 Corinthians 14:16

14:16 Otherwise, if you are praising God with your spirit, how can someone without the gift ¹  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.

[14:16]  ¹ tn Grk “how can someone who fills the place of the unlearned say ‘Amen.’”
