Christ died in the middle of the 70 week (69 1/2) to put an end to the sacrifices. Daniel speaks of this. After his death the jews were given 3.5 years to accept christ and be a light unto the world. they obviously did not and as of result the jewish leaders stoned stephen(marked end of 70th given to Israel). from then on it went to the gentiles and jews. all the promises to nation of israel were no longer in play after that because the promises came with conditions and as a people the failed. Now, remember Jesus and paul says that those who follow christ are whether jew or gentile are considered the true seeds of Abraham...the true jews. The promises will be fulfilled but to those that Follow Jesus, not to a single nation or race of people but to those that consist in the body of christ.
