2 Kings 18:1-3 In the third year of Hoshea son of Elah, king of Israel, Hezekiah the son of Ahaz, king of Judah, began to reign. 2 He was twenty-five years old when he began to reign, and he reigned twenty-nine years in Jerusalem. His mother’s name was Abi the daughter of Zechariah. 3 And he did what was right in the eyes of the Lord, according to all that David his father had done. (ESV)
Professor Avigad, a distinguished epigrapher, published a book in 1986 titled Hebrew Bullae from the Time of Jeremiah: Remnants of a Burnt Archive. The book featured a hoard of bullae discovered from the time of Jeremiah, preserved by the fires that destroyed Jerusalem in 586 BC. He always hoped to find a seal or bullae of a Judahite king, not knowing that one of the bullae featured in his book was just such a find.
