1 Corinthians 14
12 Ref So also ye, since ye are zealous of spiritual `gifts', seek that ye may abound unto the edifying of the church.
13 Ref Wherefore let him that speaketh in a tongue pray that he may interpret.
14 Ref For if I pray in a tongue, my spirit prayeth, but my understanding is unfruitful.
15 Ref What 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.
16 Ref Else if thou bless with the spirit, how shall he that filleth the place of the unlearned say the Amen at thy giving of thanks, seeing he knoweth not what thou sayest?
17 Ref For thou verily givest thanks well, but the other is not edified.
