1 Corinthians 14:11-13

New Testament for Everyone

¹¹ But if I don’t know the force of the words, I will remain a foreigner to the speaker, and the speaker will be a foreigner to me. ¹² It’s the same with you. Since you are so eager for spiritual matters, try to specialize in doing things that will build up the church.

Praying with mind as well as spirit

¹³ So the one who speaks in a tongue should pray to be able to say the same thing in clear speech.
