Matthew 5:14 in the King James Version
Ye are the light of the world. A city that is set on an hill cannot be hid.
Context
13 “You are the salt of the earth, but if the salt has lost its flavor, with what will it be salted? It is then good for nothing, but to be cast out and trodden under the feet of men.
14 “You are the light of the world. A city located on a hill can’t be hidden.
15 Neither do you light a lamp and put it under a measuring basket, but on a stand; and it shines to all who are in the house.
