“ For if we take the day as a month, just as elsewhere in prophecy days are taken as years, and in different places are used in different ways, reducing the period in the same way as has been done above to Hebrew months, we shall find the period fully made out to the 20th year of the reign of Artaxerxes, from the capture of Jerusalem. For there are given thus 185 years, and one year falls to be added to these—the year in which Nehemiah built the wall of the city. In 186 years, therefore, we find 2300 Hebrew months, as 8 years have in addition 3 intercalary months. ”
