1 Corinthians 14:2

14:2 For the one speaking in a tongue does not speak to people but to God, for no one understands; he is speaking mysteries by the Spirit. ¹ 

1 Corinthians 14:14

14:14 If ²  I pray in a tongue, my spirit prays, but my mind is unproductive.

1 Corinthians 14:27

14:27 If someone speaks in a tongue, it should be two, or at the most three, one after the other, and someone must interpret.

1 Corinthians 14:19

14:19 but in the church I want to speak five words with my mind to instruct others, rather than ten thousand words in a tongue.

[14:2]  ¹ tn Or “with the spirit”; cf. vv. 14-16.

[14:14]  ² tc ‡ Most witnesses, including some important ones (א A D^s Ψ 048 Ï lat sy bo), have γάρ (gar, “for”) here, while an equally impressive array of witnesses lack the conjunction (Ì⁴⁶ B F G 0243 1739 1881 sa). This conjunction was frequently added by scribes in epistolary literature as a clarifying word, making the connection with the preceding more explicit. As such, it has the earmarks of being a motivated reading and thus should be rejected. NA²⁷ places the word in brackets, indicating doubts as to its authenticity.
