Huldah the Prophetess (2 Kings 22, 2 Chronicles 34). When Josiah's priests found the Book of the Law in the Temple, the king's delegation did not go to Jeremiah or Zephaniah. They went to Huldah. She confirmed the book was authentic, pronounced judgment on Judah, and promised Josiah he would not live to see the disaster. Kings and high priests came to hear her.
On their voice
~622 BCE. A prophetess in Jerusalem during the great Josianic reform. She was there already when the delegation arrived — the text says she lived in the Second Quarter of Jerusalem and the delegation came to her. She speaks in the full oracle form of the classical prophets: "Thus says the LORD."
