The history of twins and our fascination with them is legendary. Although the Bible doesn’t explicitly say so, Cain and Abel are often regarded as twins; and even if they weren’t, Esau and Jacob, a bit later in the Genesis narrative, definitely were. Interestingly, it also says in the Book of Malachi that God loved Jacob but hated Esau. There is so often a chalk-and-cheese aspect to twins: Despite clearly being similar, their fates are very different.
We see this even in something like the founding of Rome: Romulus, the twin of Remus, gets all the credit (the name Rome gives that away) and finally gets taken to heaven by his father, Mars (Ares), although he has slain his twin brother, as Cain slew his brother Abel.
