Nehemiah 6:15-7:3 New International Version (NIV)
15 So the wall was completed on the twenty-fifth of Elul, in fifty-two days.
Opposition to the Completed Wall
16 When all our enemies heard about this, all the surrounding nations were afraid and lost their self-confidence, because they realized that this work had been done with the help of our God.
17 Also, in those days the nobles of Judah were sending many letters to Tobiah, and replies from Tobiah kept coming to them. 18 For many in Judah were under oath to him, since he was son-in-law to Shekaniah son of Arah, and his son Jehohanan had married the daughter of Meshullam son of Berekiah. 19 Moreover, they kept reporting to me his good deeds and then telling him what I said. And Tobiah sent letters to intimidate me.
7 After the wall had been rebuilt and I had set the doors in place, the gatekeepers, the musicians and the Levites were appointed. 2 I put in charge of Jerusalem my brother Hanani, along with Hananiah the commander of the citadel, because he was a man of integrity and feared God more than most people do. 3 I said to them, “The gates of Jerusalem are not to be opened until the sun is hot. While the gatekeepers are still on duty, have them shut the doors and bar them. Also appoint residents of Jerusalem as guards, some at their posts and some near their own houses.”
