1 Corinthians 14:10-12

Young's Literal Translation

¹⁰ There are, it may be, so many kinds of voices in the world, and none of them is unmeaning,

¹¹ if, then, I do not know the power of the voice, I shall be to him who is speaking a foreigner, and he who is speaking, is to me a foreigner;

¹² so also ye, since ye are earnestly desirous of spiritual gifts, for the building up of the assembly seek that ye may abound;
