'Signs' in the Bible

It will happen, if they will not believe even these two signs, neither listen to your voice, that you shall take of the water of the river, and pour it on the dry land. The water which you take out of the river will become blood on the dry land."

You shall take this rod in your hand, with which you shall do the signs."

Moses told Aaron all the words of Yahweh with which he had sent him, and all the signs with which he had instructed him.

Aaron spoke all the words which Yahweh had spoken to Moses, and did the signs in the sight of the people.

I will harden Pharaoh's heart, and multiply my signs and my wonders in the land of Egypt.

Yahweh said to Moses, "Go in to Pharaoh, for I have hardened his heart, and the heart of his servants, that I may show these my signs in the midst of them,

and that you may tell in the hearing of your son, and of your son's son, what things I have done to Egypt, and my signs which I have done among them; that you may know that I am Yahweh."
