Nehemiah 4:8

5 Let not their wrongdoing be covered or their sin washed away from before you: for they have made you angry before the builders.

6 So we went on building the wall; and all the wall was joined together half-way up: for the people were working hard.

7 But when it came to the ears of Sanballat and Tobiah and the Arabians and the Ammonites and the Ashdodites, that the building of the walls of Jerusalem was going forward and the broken places were being made good, they were full of wrath;

8 And they made designs, all of them together, to come and make an attack on Jerusalem, causing trouble there.

9 But we made our prayer to God, and had men on watch against them day and night because of them.

10 And Judah said, The strength of the workmen is giving way, and there is much waste material; it is impossible for us to put up the wall.

11 And those who were against us said, Without their knowledge and without their seeing us, we will come among them and put them to death, causing the work to come to a stop.
