Nehemiah 6:5

Now it came to pass, when Sanballat, and Tobiah, and Geshem the Arabian, and the rest of our enemies, heard that I had builded the wall, and that there was no breach left therein; (though at that time I had not set up the doors upon the gates;)

That Sanballat and Geshem sent unto me, saying, Come, let us meet together in some one of the villages in the plain of Ono. But they thought to do me mischief.

And I sent messengers unto them, saying, I am doing a great work, so that I cannot come down: why should the work cease, whilst I leave it, and come down to you?

Yet they sent unto me four times after this sort; and I answered them after the same manner.
