First, the prophet Isaiah, under inspiration from God, said that Cyrus is the anointed one, messiah. God relayed that Cyrus would usher the building of Jerusalem and the temple, and he did. Ezra 1-4:16, shows this to be the case, and both were being built with opposition from outsiders.
Remember, the prophecy says when the "word", proclamation goes out. And Cyrus certainly did that.
Do you understand the significance of the 70 weeks prophecy, and what specific sin is being referenced to be remedied?
Jesus did not stop all sins. People still sin today. He never referenced Daniel 9 as in him fulfilling it, and the NT doesn't reference it either.
