1 Korintus 7:35

7:35 I am saying this for your benefit, not to place a limitation on you, but so that without distraction you may give notable and constant service to the Lord.

1 Korintus 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?

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