Galatians 4:26

‘He who overcomes, I will make him a pillar in the sanctuary of My God, and he will never go out from it anymore. And I will write on him the name of My God, and the name of the city of My God, the new Jerusalem, which comes down out of heaven from My God, and My new name.

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