'Miraculous' in the Bible

"When Pharaoh says to you, "Perform a miraculous sign,' then you are to say to Aaron, "Take your staff and throw it in front of Pharaoh.' It will become a serpent."

so you may tellyour children and your grandchildren how I toyed with the Egyptians and about my miraculous signs that I performed among them, so all of youmay know that I am the LORD.

Then the LORD said, "I'm now going to make a covenant. I'll do miraculous deeds in full view of your people that haven't been done in all the earth or in any nation. All the people among whom you live will see the work of the LORD, because it's an awesome thing that I'll do with you.
