This I take from the work of Josephus on Jewish Antiquities. And I found in the beginning of the Prophet Amos the statement that he began to prophesy "in the days of Ozias, king of Judah, two years before the earthquake." What earthquake he does not clearly say. But I think the same prophet further on suggests this earthquake, when he says: "I saw the Lord standing on the altar. And He said, Strike the altar, and the doors shall be shaken, and strike the heads of all, and the remnant I will slay with the sword."
