Daniel 9:1-3

Young's Literal Translation

9 In the first year of Darius, son of Ahasuerus, of the seed of the Medes, who hath been made king over the kingdom of the Chaldeans,

² in the first year of his reign, I, Daniel, have understood by books the number of the years, (in that a word of Jehovah hath been unto Jeremiah the prophet,) concerning the fulfilling of the wastes of Jerusalem -- seventy years;

³ and I set my face unto the Lord God, to seek [by] prayer and supplications, with fasting, and sackcloth, and ashes.
