Nehemiah 6:4

6:3 So I sent messengers to them, saying, "I am doing a great work, so that I cannot come down. Why should the work cease while I leave it and go down to you?"

6:4 But they sent me this message four times, and I answered them in the same manner.

6:5 Then Sanballat sent his servant to me as before, the fifth time, with an open letter in his hand.
