Nehemiah 6:17-18

Moreover, in those days the nobles of Judah sent many letters 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 taken the daughter of Meshullam the son of Berechiah as his wife.
