'Lamp' in the Bible

And the light of a lamp will never shine in you again! And the sound of a bridegroom and bride will never be heard in you again! For your merchants were the most important people of the earth, because with your sorcery they deceived all the nations.

And the city has no need of the sun or of the moon, that they shine on it, for the glory of God illuminates it, and its lamp [is] the Lamb.

And night will not exist [any] longer, and they will not have need of the light of a lamp and the light of the sun, because the Lord God will give light to them, and they will reign {forever and ever}.
