1 Corinthians 14:16; 1 Corinthians 16:17

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?

17 I am glad of the coming of Stephanas and Fortunatus and Achaicus: for that which was lacking on your part they have supplied.
