1 Corinthians 14:16

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?

Otherwise if you bless with the spirit, how will he who fills the place of the unlearned say the "Amen" at your giving of thanks, seeing he doesn't know what you say?

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?

since, if thou mayest bless with the spirit, he who is filling the place of the unlearned, how shall he say the Amen at thy giving of thanks, since what thou dost say he hath not known?

Otherwise, if you speak a blessing in spirit, how can someone who is uninstructed say “Amen” to your thanksgiving, since he does not know what you are saying?
