TSK · Job 37:12

How many living things you have made, O LORD! You have exhibited great skill in making all of them; the earth is full of the living things you have made.

Do any of the worthless idols of the nations cause rain to fall? Do the skies themselves send showers? Is it not you, O Lord our God, who does this? So we put our hopes in you because you alone do all this.”

“I withheld rain from you three months before the harvest. I gave rain to one city, but not to another. One field would get rain, but the field that received no rain dried up.

These two have the power to close up the sky so that it does not rain during the time they are prophesying. They have power to turn the waters to blood and to strike the earth with every kind of plague whenever they want.
