Nehemiah 6:17-19

Also in those days many letters went from the nobles of Judah to Tobiah, and Tobiah’s letters came to them. For many in Judah were bound by oath to him because he was the son-in-law of Shecaniah the son of Arah, and his son Jehohanan had married the daughter of Meshullam the son of Berechiah. Moreover, they were speaking about his good deeds in my presence and reported my words to him. Then Tobiah sent letters to frighten me.
