You shall take in your hand this staff, with which you shall perform the signs [the miracles which prove I sent you].”

Moses told Aaron all the words of the Lord with which He had sent him, and all the signs that He had commanded him to do.

and Aaron said all the words which the Lord had spoken to Moses. Then Moses performed the signs [given to him by God] before the people.

And I will make Pharaoh’s heart hard, and multiply My signs and My wonders (miracles) in the land of Egypt.

Then the Lord said to Moses, “Go to Pharaoh, for I have hardened his heart and the heart of his servants [making them determined and unresponsive], so that I may exhibit My signs [of divine power] among them,

and that you may recount and explain in the hearing of your son, and your grandson, what I have done [repeatedly] to make a mockery of the Egyptians—My signs [of divine power] which I have done among them—so that you may know [without any doubt] and recognize [clearly] that I am the Lord.”
