'Hidden' in the Bible

You are the light of the world. A city located on a hill can't be hidden.

Therefore don't be afraid of them, for there is nothing covered that will not be revealed; and hidden that will not be known.

that it might be fulfilled which was spoken through the prophet, saying, "I will open my mouth in parables; I will utter things hidden from the foundation of the world."

"Again, the Kingdom of Heaven is like a treasure hidden in the field, which a man found, and hid. In his joy, he goes and sells all that he has, and buys that field.
