Nehemiah 4:6-8

So we built the wall. And all the wall was joined together to half its height, for the people had a mind to work. But when Sanballat and Tobiah and the Arabs and the Ammonites and the Ashdodites heard that the repairing of the walls of Jerusalem was going forward and that the breaches were beginning to be closed, they were very angry. And they all plotted together to come and fight against Jerusalem and to cause confusion in it.
