God did not void His covenant with Israel in 70 AD. God's promise to Abraham was repeated numerous times to his descendants and God stated it was eternal. Nothing in scripture suggests that it ceased permanently. God's future plans for Israel in prophecy proves the opposite.
This is another myth created by antisemites. They have been doing that for millennia too, just like their murders, oppression, and genocidal fantasies. Read the book of Esther and pay particular attention to Haman. I suspect that this abuse of scripture falls under the condemnation at the of the Book of Revelation.
Talk about historical ignorance!
“Incline my heart to your testimonies, and not to selfish gain!”
Psalm 119:36
