וּבְנֵ֣י קֵינִי֩ חֹתֵ֨ן מֹשֶׁ֜ה עָל֨וּ מֵעִ֤יר הַתְּמָרִים֙ אֶת־בְּנֵ֣י יְהוּדָ֔ה מִדְבַּ֣ר יְהוּדָ֔ה אֲשֶׁ֖ר בְּנֶ֣גֶב עֲרָ֑ד וַיֵּ֖לֶךְ וַיֵּ֥שֶׁב אֶת־הָעָֽם׃
摩西的岳父基尼人的子孫，同猶大人一起從棕樹城上到猶大曠野，就是在亞拉得南地的那片曠野；他們去了，就與那裡的百姓同住。
Shenei Luchot HaBerit
Cain and Abel were the first men born by woman. They were intended to be the typical "אדם" i.e. representative of what mankind should develop into. Now it had become the turn of the people of Israel to be refined and to acquire the appellation "Adam." According to our Kabbalists, Moses was the re-incarnation of Abel, הבל, whereas Yitro was the re-incarnation of Cain, חבר הקיני (see Judges 1,16, Zohar 3,216).
