'Lamp' in the Bible

Remember therefore whence thou art fallen, and repent, and do the first works: but if not, I am coming to thee, and I will remove thy lamp out of its place, except thou shalt repent.

and light of lamp shall shine no more at all in thee, and voice of bridegroom and bride shall be heard no more at all in thee; for thy merchants were the great ones of the earth; for by thy sorcery have all the nations been deceived.

And the city has no need of the sun nor of the moon, that they should shine for it; for the glory of God has enlightened it, and the lamp thereof is the Lamb.

And night shall not be any more, and no need of a lamp, and light of the sun; for the Lord God shall shine upon them, and they shall reign to the ages of ages.
