No apology, the prophecy is about Messiah, the prince. As I have repeatedly said angel said,the propheccy was about 6 things that were determined in the 70 weeks,
- 24Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy.
All these were fulfilled in Jesus and his ministry, The People Prince who was to come was a result of the Jews filling up the measure of their fathers, Matt 23, by murdering their king.
Titus was a prince in bible terms His father was emperor and Josephus constantly refers to Titus as Caesar which at that time was a title of the next in line, a bit like our Prince of Wales, or the French, Dauphin.
Actually, the prince isn't said to do anything. It his people that are the subject of the verse which was fulfilled literally to the letter. Jesus was the one who confirmed the covenant. Romans 15:8
