Exodus 9:28

Then Pharaoh called for Moses and Aaron and said, “Entreat Yahweh that He may cause the frogs to depart from me and from my people; and I will let the people go, that they may sacrifice to Yahweh.”

And Pharaoh called for Moses and Aaron and said, “Go, sacrifice to your God within the land.”

And Pharaoh said, “I will let you go, that you may sacrifice to Yahweh your God in the wilderness; only you shall not go very far away. Entreat for me.”

“So now, please forgive my sin only this once and entreat Yahweh your God, that He would only cause this death to depart from me.”

Then all the people said to Samuel, “Pray for your servants to Yahweh your God, so that we may not die, for we have added to all our sins this evil by asking for ourselves a king.”

Then the king answered and said to the man of God, “Please entreat Yahweh your God, and pray for me, that my hand may be restored to me.” So the man of God entreated Yahweh, and the king’s hand was restored to him, and it became as it was before.

“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.

“Please inquire of Yahweh on our behalf, for Nebuchadnezzar king of Babylon is warring against us; perhaps Yahweh will deal with us according to all His wonderful acts, so that the enemy will go up from us.”

And the first sounded, and there came hail and fire, mixed with blood, and they were thrown to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up.
