The 490 years of Daniel 9:24-27 stretch from the decree to restore Jerusalem in 444 B.C. to the second coming of Christ. There is a gap between the sixty-ninth and seventieth weeks in which Jesus was crucified and Jerusalem was destroyed by the Romans (Dan 9:26), In the seventieth week the antichrist will make a covenant with many but half way through the week he will break it and desecrate a temple, but in the end he himself will be destroyed (Dan 9:27).
