Nehemiah 4:7-9

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.

9But we prayed to our God and posted a guard day and night to meet this threat.
