Sanballat said to Nehemiah, "Thou hast also appointed Prophets to preach of thee at Jerusalem." Then according to Sanballat,t he first thing a Prophet is to do, is to preach for some one having been appointed to do so.
I Cor. 14:3,4, we have this concerning the work of a Prophet, "But he that prophesieth speaketh unto men to edification, and exhortation and comfort:
But he that prophesieth edifieth the church."
