10There are, it may be, so many kinds of voices in the world, and no [kind] is without signification.
11If then I know not the meaning of the voice, I shall be to him that speaketh a barbarian, and he that speaketh will be a barbarian unto me.
12So also ye, since ye are zealous of spiritual [gifts], seek that ye may abound unto the edifying of the church.
13Wherefore let him that speaketh in a tongue pray that he may interpret.
14For if I pray in a 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 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?
