Torah Talk: Bereshit

This is the record of Adam’s line.—When God created man, He made him in the likeness of God;

Rabbi Tanḥuma in the name of Rabbi Elazar, and Rabbi Menaḥem in the name of Rav said: Adam the first man learned all the crafts [in the world]. What is the source? “And craftsmen, they are me’adam” (Isaiah 44:11) – from Adam the first man. He learned even how to score a parchment, as it is stated: “This is the book” – it and its scoring.
“[This is the book of the descendants of Adam,] on the day that God created man” – this supports what Rabbi Elazar ben Azarya said: Three miracles occurred on that day: On that day they [Adam and Eve] were created, on that day they cohabited, and on that day they produced offspring.
Ben Azzai says: “This is the book of the descendants of Adam” – this verse represents the central tenet of the Torah. Rabbi Akiva says: “You shall love your neighbor as yourself” (Leviticus 19:18) – that verse represents the central tenet of the Torah, [as it teaches] that you should not say: Since I have been disparaged, let someone else be disparaged along with me; since I was cursed, let someone else be cursed along with me. Rabbi Tanḥuma said: If you do act like that, know who it is that you are disgracing: “in the likeness of God He made him” (Genesis 5:1).

Hayyim Joseph David Azulai, Chida (1724 – 1806)

The Ra'avan (Rabbi Eliezer ben Nathan [1090–1170]), of blessed memory, writes in his book (Even HaEzer, #37): " ... It seems to me that his explanation is that Ben Azzai was explaining [that] "This is the record of Adam’s line" [means] every person should love their fellow as if they were their offspring, that is to say, their child. And Rabbi Akiva says that every person should love their fellow as themselves. Ben Azzai reasons that a person loves their child more than themselves, and Rabbi Akiva reasons that a person loves themselves more than their child, and thus the rule “You shall love your neighbor as yourself” is a greater rule than "This is the record of Adam’s line".
