Isaiah 30:25-26

And on every lofty mountain and every high hill there will be brooks running with water, in the day of the great slaughter, when the towers fall. Moreover, the light of the moon will be as the light of the sun, and the light of the sun will be sevenfold, as the light of seven days, in the day when the LORD binds up the brokenness of his people, and heals the wounds inflicted by his blow.
