There is no Bible proof of this. In fact the account seems to be fairly clear that they were born at different times, that is, separate pregnancies.
Genesis 4:1-2 (King James Version)1And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD.2And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.
The 'again' would indicate a separate time, not a twin.
Another AnswerKayin(aka Cain) and Habel(aka Abel) may or may not have been twins, I think if it was important YAHVEH would have let us know.But the word for Again is Yasephmeans Add like Yoseph-(aka Joseph meaning 'let him add') and yes it also means 'continue', BUT it also means 'conceive again' and many other words, so we can't just pick the one we want to pick.
Some people think Cain is from Satan because Eve was beguiled(tricked)-so nothing is further from the truth, as for as Chavah-(aka Eve) the Hebrew word for beguile is naw-saw and it means: to lead astray, that is, (mentally) to delude, or (morally) to seduce: - beguile, deceive, greatly, utterly etc.
NOT seduced physically as sex, and HaSatan-(aka the Devil) wasn't a serpent until after God punished him, no one knows what he looked like before, probably very nice.
Another AnswerThere is no Bible proof of this. The (original) Hebrew script is ambiguous and therefor it cannot be determined if Cain and Abel were twins or not. This is because that it says that Eve continued giving birth but it does not indicate if it was a direct continuation (twins) or a late continuation (regular siblings).Answer: Nowhere in the Bible is it stated that Cain and Abel had twin sisters.
Cain
1) Esau and Jacob (Genesis ch.25) 2) Zerach and Peretz (Genesis ch.38).
Cain killed abel. the first book of the bible genesis
the story, or history of Cain and Abel is in Genesis Chapter 4.
Abel
Abel
They could have been twins, or it could be that the Bible does not speak of the second time.
Cain had no choice but to marry his sisters and have children.
Abel was Cain's little brother. Cain killed Abel because he was jealous of Abel. You can find this incident in Genesis chapter 4.
The bible mentions Seth, but not all the others. He either married a sister or a close relative.
It is not known for sure if Cain and Abel are twins. The Bible mentions only one conception, but two births, which gives many theologians the belief that they were indeed twins.Another Answer:From the Hebrew word for 'later or again' - 'Yaseph - which means continue or conceive again, it doesn't appear so. In any event, there were two sons/brothers for the main point of their stories:Genesis 4:1-2New King James Version (NKJV)Cain Murders Abel4 Now Adam knew Eve his wife, and she conceived and bore Cain, and said, "I have acquired a man from the Lord." 2 Then she bore again, this time his brother Abel. Now Abel was a keeper of sheep, but Cain was a tiller of the ground.
According to the Bible, Cain killed Abel because he was jealous that Abel's sacrifice was accepted by God, while Cain's was rejected. "And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him." - Genesis 4:8
