2 in the first year of his reign, I, Daniel, perceived in the books the number of years that, according to fthe word of the Lord to Jeremiah the prophet, must pass before the end of the desolations of Jerusalem, namely, seventy years.

3 Then I turned my face to the Lord God, seeking him by gprayer and pleas for mercy with fasting and sackcloth and ashes.
