Nehemiah 6:16-19

And it came to pass, when all our enemies heard thereof, that all the nations that were about us feared, and were much cast down in their own eyes; for they perceived that this work was wrought of our God. Moreover in those days the nobles of Judah sent many letters unto Tobiah, and the letters of Tobiah came unto them. For there were many in Judah sworn unto 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 to wife. Also they spake of his good deeds before me, and reported my words to him. And Tobiah sent letters to put me in fear.
