Did any woman perform a miracle in the Old Testament?

Answer:

If you include the gift of prophecy, then several women are mentioned in the Old Testament as being prophetesses: Miriam (Exodus 15:20), Deborah (Judges 4:4), Huldah (II Kings 22:14; II Chronicles 34:22), and Isaiah's wife (Isaiah 8:3).

If you are looking for events that go against nature, such as miraculous healings, bringing water from rocks, etc. then I don't know of any.
