'Wonders' in the Bible

And I will put forth my hand, and smite Egypt with all my wonders which I will do in the midst thereof: and after that he will let you go.

And Jehovah said unto Moses, When thou goest back into Egypt, see that thou do before Pharaoh all the wonders which I have put in thy hand: but I will harden his heart and he will not let the people go.

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

And Jehovah said unto Moses, Pharaoh will not hearken unto you; that my wonders may be multiplied in the land of Egypt.

And Moses and Aaron did all these wonders before Pharaoh: and Jehovah hardened Pharaoh's heart, and he did not let the children of Israel go out of his land.

Who is like unto thee, O Jehovah, among the gods? Who is like thee, glorious in holiness, Fearful in praises, doing wonders?
