It's been three days since Avraham's circumcision. He is in pain, sweating in the midday heat, when G-d comes to visit him. Then three strangers appear in the distance, and Avraham runs toward them, brings them into his tent, and spends hours hosting them. G-d waits.

The question at the center of this episode is how that is anything other than a profound act of disrespect towards the Creator. Rabbi Epstein traces what Avraham’s actions actually mean.

Avraham has already passed nine of his ten tests, and G-d is standing in front of him with a covenant that will be stamped into the flesh of every Jewish male for the rest of history. The questions that come out of this moment are not small ones.

Why does the covenant take the form it does? Why does it happen at eight days old, before a child can consent or even understand? Why did Avraham himself wait so long, given that he understood the Torah long before Sinai? The answer to that last question comes from an explanation Rabbi Epstein first encountered in high school, and it turns on a Talmudic principle about commandments and merit. It also points to a short list of mitzvos that share a strange quality with circumcision: they can only be performed once.

Then there is Avraham's plea on behalf of Ishmael. On the surface it reads as a father asking that his older son not be cast aside. But Rabbi Epstein traces the request to something far larger: Avraham's understanding of the four exiles, Esau's conditional claim over the Jewish people, and why Ishmael's continued presence in the world may be exactly what allows the Jewish people to be redeemed when the time comes, without having to be perfect first.

Avram is 99 years old when Hashem appears to him with a new name for Himself, El Shaddai, and an interesting command: walk before Me and be perfect. Rabbi Epstein and Tom spend this episode unpacking what that actually asks of a person, and why Rashi reads "walk before Me" as something more demanding than walking with G-d, and what separates Avram's path from Noach's.

The verse goes on to talk about circumcision, and Rabbi Epstein relates the Talmud's exchange between Rabbi Akiva and a Roman about whether a perfect Creator would make an imperfect creation.

Finally, we learn about the three spiritual safeguards of the land of Israel hidden inside the second blessing of Birkas Hamazon, and why the Crusaders lost Jerusalem to a people who shared at least one thing with Avraham's descendants.
