1 Corinthians 14:16
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ἐπεὶ ἐὰν εὐλογήσῃς τῷ πνεύματι, ὁ ἀναπληρῶν τὸν τόπον τοῦ ἰδιώτου πῶς ἐρεῖ τὸ Ἀμὴν ἐπὶ τῇ σῇ εὐχαριστίᾳ, ἐπειδὴ τί λέγεις οὐκ οἶδεν;
Otherwise, if you speak a blessing in spirit (note: Or in the Spirit), how can someone who is uninstructed say “Amen” to your thanksgiving, since he does not know what you are saying?
