Nehemiah 6:15-17

15So the wall was finished on the twenty-fifth of Elul, in fifty-two days.

16And it came to pass that when all our enemies heard [of it], all the nations that were about us were afraid and were much cast down in their own eyes, and they perceived that this work was wrought by our 1God.

17Moreover in those days the nobles of Judah sent many letters to Tobijah, and those of Tobijah came to them.
