Nehemiah 6:15

ALL ENEMIES FRUSTRATED; THE WALL FINISHED

"So the wall was finished in the twentieth and fifth day of Elul, in fifty-two days. 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 the 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 Shechaniah the son of Arah; and his son Jehohanan had taken the daughter of Meshullum 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."

Here we have the explanation of the priesthood's hatred of Nehemiah. Tobiah had married one of their daughters and was the son-in-law of Shechaniah. Many of them were sworn allies of Tobiah and cooperated with Israel's enemies throughout the period of rebuilding the wall. Indeed, its completion was certainly wrought of God (Nehemiah 6:16).
