Dan 9:2

9:2 the desolations of Jerusalem . . . seventy years. Interpreters differ on the dates of the beginning and ending of the seventy-year period, and on whether it is to be understood as a round number for a human lifetime or exactly seventy years. Some date the period from 586 b.c. (the destruction of Jerusalem by Nebuchadnezzar) to 516 b.c., when the restoration of the temple was completed under Zerubbabel (Ezra 6:13–18). Others date the beginning of the period to the year of Daniel’s own captivity (605 b.c., 1:1 note), which would suggest that Daniel recognized the end of the seventy years was imminent.
