Exodus 7:16

“And you shall take in your hand this staff, with which you shall do the signs.”

“So I said to you, ‘Let My son go that he may serve Me’; but you have refused to let him go. Behold, I will kill your son, your firstborn.”’”

And afterward Moses and Aaron came and said to Pharaoh, “Thus says Yahweh, the God of Israel, ‘Let My people go that they may celebrate a feast to Me in the wilderness.’”

“But Pharaoh will not listen to you. And I will set My hand upon Egypt and bring out My hosts, My people the sons of Israel, from the land of Egypt by great judgments.

and His signs and His works which He did in the midst of Egypt to Pharaoh the king of Egypt and to all his land;

He permitted no man to oppress them, And He reproved kings for their sakes,

“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.
