1 Corintios 14

So if you, in using a strange tongue, say words which have no sense, how will anyone take in what you are saying? for you will be talking to the air.

Así también vosotros, si por la lengua no diereis palabra bien significante, ¿cómo se entenderá lo que se dice? porque hablaréis al aire.

So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air.

So also you, unless you uttered by the tongue words easy to understand, how would it be known what is spoken? For you would be speaking into the air.
