Nehemiah 6
17 Ref Moreover in those days the nobles of Judah sent many letters to Tobiah, and [the letters] of Tobiah came to them.
18 Ref For there were many in Judah sworn 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 wife.
19 Ref Also they spoke of his good deeds before me, and reported my words to him. Tobiah sent letters to put me in fear.
