'Sixty two' in the Bible

So Darius the Mede received the kingdom; he was about the age of sixty-two.

So you are to know and understand that from the issuance of the command to restore and rebuild Jerusalem until [the coming of] the Messiah (the Anointed One), the Prince, there will be seven weeks [of years] and sixty-two weeks [of years]; it will be built again, with [a city] plaza and moat, even in times of trouble.

Then after the sixty-two weeks [of years] the Anointed One will be cut off [and denied His Messianic kingdom] and have nothing [and no one to defend Him], and the people of the [other] prince who is to come will destroy the city and the sanctuary. Its end will come with a flood; even to the end there will be war; desolations are determined.
