Daniel,
“Seventy weeks are determined for your people and for your holy city,
Yes, it is fulfilled, but there are some very good but different calculations given by a number of great commentators. I believe Tertullian did well interpreting the seventy weeks. I will only point out the highlights.
- This calculation begins with the first year of Darius, since that was the time when the vision itself was revealed to Daniel, to the day when Christ was born, and the total figure of four hundred and thirty-seven years and five months. This means that sixty-two and a half weeks were used up, or the equivalent of four hundred and thirty-seven years and six months.
- Then eternal righteousness was revealed, and the Saint of saints was anointed, namely Christ, and the vision and prophecy were sealed, and those sins were remitted which are allowed through faith in Christ’s name to all who believe in Him.
- the seven and a half weeks, which in turn are divided up into a subsection of earlier weeks
Well, after Augustus, who lived on after Christ’s birth, fifteen years elapsed.
He was succeeded by Tiberius Caesar, and he held sway for twenty-two years, seven months and twenty-eight days.
In the fifteenth year of his reign Christ suffered, being about thirty-three when He suffered.
Then there was Gaius Caesar, also named Caligula, who reigned for three years, eight months and thirteen days.
Nero reigned for nine years, nine months and thirteen days. Galba ruled for seven months and twenty-eight days;
Otho for three months and five days; and Vitellius for eight months and twenty-eight days.
Vespasian vanquished the Jews in the first year of his reign, bringing the number of years to a total of fifty-two, plus six months. For he ruled for eleven years, and so by the date of his storming Jerusalem, the Jews had completed the seventy weeks foretold by Daniel.
That’s more or less it - the seventy weeks are a re-interpretation of Jeremiah’s “seventy years” (i.e. the length of an average lifetime - cf. Psalm 90) of the Exile.
