Conspiracy Against Nehemiah
6:1 Now 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), 2 Sanballat 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. 3 And 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?” 4 And they sent to me four times in this way, and I answered them in the same manner.
