Daniel 9:1-5

In the first year of Darius the son of Ahasuerus, of Median descent, who was made king over the realm of the Chaldeans— in the first year of his reign, I, Daniel, understood from the books the number of years which, according to the word of the LORD to Jeremiah the prophet, must pass before the desolations [which had been] pronounced on Jerusalem would end; and it was seventy years. [Jer 25:11, 12; 29:10] So I directed my attention to the Lord God to seek Him by prayer and supplications, with fasting, sackcloth and ashes. I prayed to the LORD my God and confessed and said, “O Lord, the great and awesome God, who keeps His covenant and extends lovingkindness toward those who love Him and keep His commandments, we have sinned and committed wrong, and have behaved wickedly and have rebelled, turning away from Your commandments and ordinances.
