7Even things without life, having a voice, such as a music-pipe or other instrument, if they do not give out different sounds, who may be certain what is being played?
8For if the war-horn gives out an uncertain note, who will get ready for the fight?
9So 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.
10There are, it may be, a number of different voices in the world, and no voice is without sense.
11But if the sense of the voice is not clear to me, I am like a man from a strange country to him who is talking, and he will be the same to me.
12So if you are desiring the things which the Spirit gives, let your minds be turned first to the things which are for the good of the church.
13For this reason, let the man who has the power of using tongues make request that he may, at the same time, be able to give the sense.
