Exodus 10:23

“But on that day I will make a distinction for the land of Goshen, where My people are living, so that no swarms of flies will be there, that you may know that I, Yahweh, am in the midst of the land.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.

“And when I extinguish you, I will cover the heavens and darken their stars; I will cover the sun with a cloud, And the moon will not give its light.

“And I also withheld the rain from you While there were still three months until harvest. Then I would send rain on one city, And on another city I would not send rain; One portion would be rained on, While the portion not rained on would dry up.

And the fourth angel sounded, and a third of the sun and a third of the moon and a third of the stars were struck, so that a third of them would be darkened and the day would not shine for a third of it, and the night in the same way.
