Nehemiah 4:6-8

6So we rebuilt the wall till all of it reached half its height, for the people worked with all their heart. 7But when Sanballat, Tobiah, the Arabs, the Ammonites and the people of Ashdod heard that the repairs to Jerusalem’s walls had gone ahead and that the gaps were being closed, they were very angry. 8They all plotted together to come and fight against Jerusalem and stir up trouble against it.
