8 For if the war-horn gives out an uncertain note, who will get ready for the fight?
9 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.
10 There are, it may be, a number of different voices in the world, and no voice is without sense.
11 But 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.
12 So 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.
13 For 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.
14 For if I make use of tongues in my prayers, my spirit makes the prayer, but not my mind.
