'Signs' in the Bible

And it shall come to pass, if they will not believe even these two signs, neither hearken unto thy voice, that thou shalt take of the water of the river, and pour it upon the dry land: and the water which thou takest out of the river shall become blood upon the dry land.

And thou shalt take in thy hand this rod, wherewith thou shalt do the signs.

And Moses told Aaron all the words of Jehovah wherewith he had sent him, and all the signs wherewith he had charged him.

and Aaron spake all the words which Jehovah had spoken unto Moses, and did the signs in the sight of the people.

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

And Jehovah said unto Moses, Go in unto 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 thou mayest tell in the ears of thy son, and of thy son's son, what things I have wrought upon Egypt, and my signs which I have done among them; that ye may know that I am Jehovah.
