Nehemiah 6:1-3

1Now when Sanballat and Tobiah and Geshem the Arab and the rest of our enemies heard that I had built the wall and that there was no breach left in it (although up to that time I had not set up the doors in the gates),

2Sanballat and Geshem sent to me, saying, "Come and let us meet together at Hakkephirim in the plain of Ono." But they intended to do me harm.

3And I sent messengers to them, saying, "I am doing a great work and I cannot come down. Why should the work stop while I leave it and come down to you?"
