Bede : The Jews said, "This temple was built in forty-six years, and you will raise it up in three days?" They answered as they understood. But lest we too should perceive our Lord's spiritual word in a carnal way, the Evangelist subsequently explained what temple it was of which he was speaking. As for their stating that the temple was built in forty-six years, they meant not its first but its second building. For Solomon, the first [builder], finished the temple very rapidly within seven years, during a time of great peace in his kingdom. It was destroyed by the Chaldeans, but after seventy years it began to be rebuilt, at the bidding of Cyrus the Persian, when the captivity was lightened. But the descendants of those who were deported were unable to finish the work that they were doing under the rulers Zerubbabel and Jeshua before forty-six years had passed, on account of the resistance of the neighboring nations.This number [forty-six] of years is also most apt for the perfecting of our Lord's physical body. Writers on natural history tell us that the form of the human body is completed within this number of days. During the first six days after conception it has a likeness to milk; during the following nine days it is changed into blood; next, in twelve days, it becomes solid; during the remaining eighteen days it is formed into the perfect features of all its members; and after this, during the time remaining until birth, it increases in size. Six plus nine plus twelve plus eighteen makes forty-five. If to this we add one, that is, the day on which the body, divided into its separate members, begins to grow, we find the same number of days in the building up of our Lord's body as there were years in the construction of the temple. — Homilies on the Gospels 2.1
