The Targum of Jerusalem says, the subject of contention was that Cain denied a Judgment to come and Eternal Life; and Abel argued for both.[109] The Rabbi Menachem, however, asserts that the point on which they strove was whether a word was written _zizit_ or _zizis_ in the Parascha.[110] “And when they were in the field together, the brothers quarrelled, saying, ‘Let us divide the world.’ One said, ‘The earth you stand on is my soil.’ The other said, ‘You are standing on my earth.’ One said, ‘The Holy Temple shall stand on my lot;’ the other said, ‘It shall stand on my lot.’ So they quarrelled. Now there were born with Abel two daughters, his sisters. Then said Cain, ‘I will take the one I choose, I am the eldest;’ Abel said, ‘They were born with me, and I will have them both to wife.’ And when they fought, Abel flung Cain down and was above him; and he lay on Cain. Then Cain said to Abel, ‘Are we not both sons of one father; why wilt thou kill me?’ And Abel had compassion, and let Cain get up. And so Cain fell on him and killed him. From this we learn not to render good to the evil, for, because Abel showed mercy to Cain, Cain took advantage of it to slay Abel.”[111] S. Methodius the Younger refers to this tradition. He says: “Be it known that Adam and Eve when they left Paradise were virgins. But the third year after the expulsion from Eden, they had Cain, their first-born, and his sister Calmana; and after this, next year, they had Abel and his sister Deborah. But in the three hundredth year of Adam’s life, Cain slew his brother, and Adam and Eve wailed over him a hundred years.”[112] Eutychius, Patriarch of Alexandria, says, “When Adam and Eve rebelled against God, He expelled them from Paradise at the ninth hour on Friday to a certain mountain in India, and He bade them produce children to increase and multiply upon the earth. Adam and Eve therefore became parents, first of a boy named Cain, and of a girl named Azrun, who were twins; then of another boy named Abel, and of a twin sister named Owain, or in Greek Laphura. “Now, when the children were grown up, Adam said to Eve, ‘Let Cain marry Owain, who was born with Abel, and let Abel have Azrun, who was born with Cain.’ But Cain said to his mother, ‘I will marry my own twin sister, and Abel shall marry his.’ For Azrun was prettier than Owain. But when Adam heard this, he said, ‘It is contrary to the precept that thou shouldst marry thy twin sister.’
