Daniel 3:12 There are certain Jews whom thou hast set over the affairs of the province of Babylon, Shadrach, Meshach, and Abed-nego; these men, O king, have not regarded thee: they serve not thy gods, nor worship the golden image which thou hast setup.

Matthew 5:13-16 13.Ye are the salt of the earth: but if the salt have lost its savor, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and trodden under foot of men. 14. Ye are the light of the world. A city that is set on a hill cannot be hid.
