Pray to god asked for mercy for us

Exodus 10:12-29
Moses stretched out his staff over Egypt and the Load made an east wind blow across the land all day and all night, by the morning the wind brought the locusts.
Plague of Locusts- Nothing green remained on tree or plant in all the land of Egypt.
Pharaoh said to Moses: I have sinned against the Load your God and again you.
strong west wind carried locusts into the red sea.
Moses stretch out his staff toward the sky so the darkness covered all Egypt for 3 days. 9th Plague. This darkness can be felt.
Pharaoh agree your women, children may go with you, only leave your flocks and herds behind.
Pharaoh said to Moses," Go out of my sight, make sure you don't appear before me again! The day you see my face will die"
Moses replied,"Just as you said, I will never appear before you again"
Never before had there been such a plague of ---, nor will there ever be again.
Why?
God's work not made by man's hand. So it is great thing beyond imagination of human being.
Plague of Locusts let Egypt really ruined, left nothing in the field and livestock were died.
After 9 plagues, Pharaoh angry to Moses, don;t want to see Moses again, for he always bring diaster to him.
The darkness probably a khamsin duststrom, blocked the sun. so it is can be felt.
Those plagues occurred a period of six months to a year.
In each case God chose to use natural disorders to confound Pharaoh and the gods of Egypt.
The flog to bring disease, 'Nile-god' to bring ruin, not prosperity.
How?
When heart of one's hardened, not any miraculous sign may change his mind, only way is pray to the Load. For the Load may change people's mind. God decides everything His is the Load.
When people can't face the failure might turn to angry to the people who confronted.
I only can do is ask great God have mercy on us and the people living in darkness.
