Daniel 9:1-3

These things happened during the first year Darius son of Xerxes was king over Babylon. He was a descendant of the Medes. During Darius’ first year as king, I, Daniel, was reading the Scriptures. I saw that the LORD told Jeremiah that Jerusalem would be empty ruins for seventy years. Then I turned to the Lord God and prayed and asked him for help. To show my sadness, I fasted, put on rough cloth, and sat in ashes.
