I Coríntios 14:16

16 Otherwise when you are praising God in the Spirit, how can someone else, who is now put in the position of an inquirer, The Greek word for [inquirer] is a technical term for someone not fully initiated into a religion; also in verses 23 and 24. say "Amen" to your thanksgiving, since they do not know what you are saying?

16 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?
