1 Corinthians 14:16
King James Version
“Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest?”
Context
13Wherefore let him that speaketh in an tongue pray that he may interpret.
14For if I pray in an tongue, my spirit prayeth, but my understanding is unfruitful.
15What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
16Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest?
17For thou verily givest thanks well, but the other is not edified.
18I thank my God, I speak with tongues more than ye all:
19Yet in the church I had rather speak five words with my understanding, that I might teach others also, than ten thousand words in an tongue.
