Exodus 7:9

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

So Moses and Aaron came to Pharaoh, and thus they did just as Yahweh had commanded; and Aaron threw his staff down before Pharaoh and his servants, and it became a serpent.

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;

“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.
