1 Corinthians 14:11–16

11 Therefore, if I do not know the meaning of the language, I will be a foreignerG to the speaker, and the speaker will be a foreigner to me. 12 So also you—since you are zealouse for spiritual gifts,H,f seek to excel in building up the church.

13 Therefore the person who speaks in a tongue should pray that he can interpret. 14 For if I pray in a tongue, my spiritg prays, but my understanding is unfruitful.h 15 What then? I will pray with the spirit, and I will also pray with my understanding. I will sing praise with the spirit, and I will also sing praise with my understanding. 16 Otherwise, if you praise with the spirit,A how will the outsiderB say “Amen”i at your giving of thanks, since he does not know what you are saying?
