Abraham’s covenant is forever.

“He remembers His covenant forever, The word which He commanded, for a thousand generations, The covenant which He made with Abraham, And His oath to Isaac, And confirmed it to Jacob for a statute, To Israel as an everlasting covenant, Saying, “To you I will give the land of Canaan As the allotment of your inheritance,””
‭‭Psalms‬ ‭105‬:‭8‬-‭11‬ ‭NKJV‬‬
