Nehemiah 4:9

7But when Sanballat, Tobiah, the Arabians, the Ammonites, and the Ashdodites heard that the repairing of the walls of Jerusalem went forward, and that the breaches began to be filled, they were very angry;

8and they all conspired together to come and fight against Jerusalem, and to cause confusion among us.

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

10Judah said, “The strength of the bearers of burdens is fading and there is much rubble, so that we are not able to build the wall.”

11Our adversaries said, “They will not know or see, until we come in among them and kill them, and cause the work to cease.”
