1 Corinthians 14:16
Patriarchal Greek New Testament (1904) · 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 οἶδε·
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?
