Haweis(i)
12 So also ye, if ye zealously affect spiritual gifts, seek that ye may abound in them for the edification of the church.
13 Therefore let him who speaketh in an unknown tongue, pray that he may interpret also.
14 For if I pray in an unknown tongue, my spirit prayeth, but my mind produces no fruit.
15 What then is my object? I will pray with the spirit, and I will pray with the understanding also: I will sing psalms with the spirit, and I will sing psalms with the understanding also.
16 Else, though thou bless God in spirit, how shall he who filleth the place of an illiterate man, say Amen after thy thanksgiving, seeing he knoweth not what thou sayest?
17 For thou indeed givest thanks to God well, but another man is not edified by it.
