It is said in the esoteric knowledge of the Torah---that God dressed Adam and Eve in robes of rabbit fur -- eventually, they were worn by good and bad folks throughout history. However, the robes or garments did not appear again until the blessing of Jacob, and because they smelled of the wonderous fragrances of the Garden of Eden, which Isaac recognized, thus, the fragrance overwhelmed the aging and blind Isaac to see Jacob as his son Esau whom was told to hunt game and prepare him a meal.
In the 1,000 years of the coming peace here on earth, the fragrance of the Garden of Eden would once again be known and all the righteous descendants of Noah--Shem, Japheth and Ham. Thus, 3 rabbits sharing in the world to come without war, hunger, illness, ignorance or pain, etc.
Shem became a prophet of God and lived 600 yrs, serving God as a righteous Noahide or God-Fearer as the king (Malkitzedek, the "Just King") of Salem (future city of Jerusalem), whom brought offerings to God as did his ancestors. He established the Academy of Shem and Eber and the words of the Noah Covenant were passed among all those around the globe by the descendants of Abraham and Sarah. Hagar eventually returned to Abraham as Keturah and became a God-Fearer and lived by the Noah laws as found in the Book of Acts too, as well as in the Qur'an, ancient Chinese writings and in documents found in the Dead Sea Scrolls dated from 450 bce to 110 ce.
