Then ¹  I looked when the Lamb opened the sixth seal, and a huge ²  earthquake took place; the sun became as black as sackcloth made of hair, ³  and the full moon became blood red; ⁴ 

Then ¹  a great sign appeared in heaven: a woman clothed with the sun, and with the moon under her feet, and on her head was a crown of twelve stars. ² 

The city does not need the sun or the moon to shine on it, because the glory of God lights it up, and its lamp is the Lamb.

Then ¹  the fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of them were darkened. And there was no light for a third of the day ²  and for a third of the night likewise.
