Miriam

(30) And the seven prophetesses that prophecied to Israel, who were they? Sarah, Miriam, Deborah, Hannah, Abigail, Huldah and Esther. . Miriam, as it is written (Ex. 15, 26) Then took Miriam the prophetess, the sister of Aaron. Was she then Aaron's and not Moses' sister." "This means," said R. Nachman, in the name of Rab, "that she had prophecied even when she had been only Aaron's sister [before Moses' birth] saying, 'In the future my mother will give birth to a child that will deliver the Israelites.' Finally, when Moses was born, the whole house was filled with light, and her father arose, and kissed her on her head, and saying to her, 'My daughter, thy prophecy is fulfilled.' Afterward, when he was cast into the river, her mother rose, saying to her, 'My daughter, what has become of thy prophecy?' And thus we understand the passage (Ib. 2, 4) And his sister placed herself afar off, to ascertain what would be done to him, to mean to know what would be the outcome of her prophecy."

(2) הנביאה, the term נביא or נביאה is accorded to people who either are held in high esteem by their peers for their eloquence or their ability to admonish their peers.

(1) "And Miriam the Prophetess took." Where had she prophesied? When she was the sister of Aaron, before Moses was born, she said, 'In the future, my mother will give birth to a son, etc.' Like there in Sota (13a), another reason, she was called the sister of Aaron because he gave his soul to her when she had leprosy, she was called by his name.

(2) ככל אשר יורו אתכם, for you are to remember what happened to Miriam, certainly a highly placed person, who, in spite of being a prophetess, and the leader of all the Israelite women, and Moses’ own sister, was not accorded preferential treatment in this regard. She was segregated for seven days, as we know from Numbers 12,14.
