The Torah tells us, "Cain departed from the presence of the Lord, and lived in the land of Nod, east of Eden" (Genesis 4:16). But where did he really go?

The Rabbis of the Bereshit Rabbah, a collection of ancient rabbinic interpretations of Genesis, grapple with this very verse. "Cain departed from the presence of the Lord," it says. But how could he? God's presence is everywhere!

Rabbi Yudan, quoting Rabbi Aivu, offers a powerful image: Cain cast God’s rebuke behind him, as if he could deceive the Most High. Imagine that – the audacity! He’s not just leaving; he's trying to outsmart the Divine.

Rabbi Berekhya, in the name of Rabbi Elazar ben Rabbi Shimon, adds another layer. He says Cain departed "as one who shows a split hoof." Think of a pig, trying to appear kosher by displaying its split hooves, even though it doesn’t chew its cud (another requirement for being kosher). Cain, according to this interpretation, is putting on a show of humility, but inside, he remains arrogant and unrepentant. It's a fascinating image of outward appearance versus inner reality.

But then, the interpretation takes an unexpected turn. Rabbi Ḥama, citing Rabbi Ḥanina bar Rabbi Yitzḥak, suggests that Cain departed joyfully! He connects it to the verse in Exodus 4:14, "Here he is going out [yotze] to meet you [and he will see you and he will rejoice in his heart]." Is Cain actually happy to be free from God's judgment?

And here's where the story gets truly remarkable. According to this midrash, Adam, the first man, encounters Cain. Adam asks him, "What became of your sentence?" Cain replies, "I repented and reached a settlement." Can you imagine Adam's reaction? The text says Adam began beating himself on the face, exclaiming, "Such is the power of repentance, and I did not know!"

Think about that for a moment. Adam, who ate from the Tree of Knowledge and brought sin into the world, hadn't grasped the power of teshuva, repentance. Yet, Cain, a murderer, found redemption.

Immediately, the text says, Adam stood and recited, "A psalm, a song for the Shabbat day…" (Psalms 92:1). Rabbi Levi tells us that Adam actually composed this psalm, but it was forgotten until Moses reintroduced it. Interestingly, the first letters of the Hebrew words "Mizmor shir leyom haShabbat" (A psalm, a song for the Shabbat day) – mem, shin, lamed, heh – can be combined to spell "leMoshe" – to Moses. A subtle connection across generations.

The psalm itself becomes a meditation on this encounter. "A psalm, a song for the Shabbat day. It is good to give thanks [lehodot] to the Lord…" The Rabbis cleverly expound on the word "lehodot," connecting it to confession [vidui]. So, the psalm becomes not just a song of thanksgiving, but also a song of repentance.

What a powerful story! It's a reminder that even after the most terrible deeds, repentance is possible. It’s also a poignant reflection on how we often underestimate the power of forgiveness, both divine and human. And perhaps, it's a call for us to examine our own hearts: Are we like Cain, putting on a show while hiding our true selves? Or are we striving for genuine teshuva, embracing the transformative power of repentance and return?
