Nehemiah 6:15-18 ESV
So the wall was finished on the twenty-fifth day of the month Elul, in fifty-two days. And when all our enemies heard of it, all the nations around us were afraid and fell greatly in their own esteem, for they perceived that this work had been accomplished with the help of our God. 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.
