Luke 8:16-18

Now no one, lighting a candle, covers it with a container, or sets it under a bed. Instead, he places it on a lampstand, so that those who enter may see the light. For there is nothing secret, which will not be made clear, nor is there anything hidden, which will not be known and be brought into plain sight. Therefore, take care how you listen. For whoever has, it will be given to him; and whoever does not have, even what he thinks he has will be taken away from him."
