Nehemiah 4:7-9

7Now it happened, when Sanballat, Tobiah, the Arabs, the Ammonites, and the Ashdodites heard that the walls of Jerusalem were being restored and the gaps were beginning to be closed, that they became very angry,

8and all of them conspired together to come and attack Jerusalem and create confusion.

9Nevertheless we made our prayer to our God, and because of them we set a watch against them day and night.
