"In 2005, for instance, researchers discovered a coin from the period of the First Revolt against the Romans, prior to the destruction of the Second Temple, bearing the phrase "For the Redemption of Zion". They also found Hebrew letters on a jar fragment of the First Temple period, a Hasmonean coin inscribed with the words "Yehonatan High Priest, friend of the Jews," and more. Other finds over the years include seals inscribed with Hebrew and Jewish names - including of at least two people mentioned in the Book of Jeremiah."
