The Long Wait

Abraham was seventy-five when God first called him from his homeland. He was eighty-six when Ishmael was born. He was ninety-nine years old when God finally commanded circumcision. In the intervening years, Abraham had walked the length of Canaan, traveled to Egypt, fought a coalition of kings, received divine promises about his descendants, and entered into a covenant marked only by the divided animals of a ritual sacrifice. All of that happened before a single letter about circumcision.

The question the Mekhilta asked was obvious: why so late? If the covenant of circumcision was this important, if it was to become the foundational physical mark of the Jewish people for all generations, why not command it on the first day? Why give Abraham decades of life and spiritual development before adding this requirement?

The Answer That Was Not About Abraham

The Mekhilta's answer looked past Abraham entirely. The delay was not for his sake. It was for the sake of people who did not yet exist, in nations that did not yet have a relationship to God, who would one day want to enter the covenant and be concerned that they had lost their chance.

God waited until Abraham was ninety-nine so that a potential convert at age twenty, or thirty, or sixty, could say: I am not too old. Abraham was not circumcised until he was ninety-nine. The covenant was available to him at that age, and the covenant is available to me now. The late date of the commandment was a standing invitation addressed to every future human being who might otherwise have calculated that they had arrived too late for the door to still be open.

Why Converts Are Loved

The Mekhilta paired this teaching with a broader reflection on the Torah's treatment of converts. The Torah exhorts Israel to love and protect the stranger, the ger, in verse after verse. "And a stranger you shall not afflict" (Exodus 22:20). "And you shall love the stranger" (Deuteronomy 10:19). "And you have known the soul of the stranger" (Exodus 23:9). Rabbi Eliezer explained the repetition: the convert has left everything behind. Former community, former religion, former identity. No family connections in Israel, no ancestral land, no established reputation. The social capital that native-born Jews inherit does not exist for a convert, and this vulnerability is precisely why God keeps returning to the theme of their protection.

A convert is, in the Mekhilta's framing, beloved because the decision to join is entirely volitional. The born Israelite did not choose to be born Israelite. The convert made an active choice, in full knowledge of the cost, and came anyway. That willingness is worth something. God made visible provision for it by ensuring that the foundational physical mark of the covenant was commanded late enough that no one could claim the timing left them out.

Abraham's Hesitation

Abraham himself needed reassurance. The tradition preserves that he was not immediately enthusiastic. He had spent his life trying to bring people closer to the one God, building relationships across the full range of human community. A permanent physical mark that distinguished his body from others raised a concern about separation, about creating a visible barrier between himself and the people he was trying to reach.

God's response was theological: let it suffice that I am your God, as I am God of the world. The mark was not a sign of separation from humanity but of particular covenant. Abraham's concern for the unconverted was real, and God addressed it. The circumcision would not close the door. The late timing had already ensured that.

Mekhilta Tractate Nezikin 18:3Mekhilta DeRabbi Yishmael

Beloved are the strangers, the converts to Judaism. The Mekhilta emphasizes how many times the Torah exhorts Israel to treat them well. "And a stranger you shall not afflict" (Exodus 22:20). "And you shall love the stranger" (Deuteronomy 10:19). "And you have known the soul of the stranger" (Exodus 23:9). The repetition is deliberate and meaningful.

Rabbi Eliezer explained why the Torah returns to this theme so persistently: because a stranger's past is to his disadvantage. The convert has left behind his former community, his former religion, his former identity. He arrives in Israel without the social capital that native-born Jews possess, no family connections, no ancestral land, no established reputation. He is starting from nothing.

This vulnerability is precisely why the Torah commands Israel to protect him, not once, but repeatedly. A single command might be forgotten or downplayed. Multiple commands, scattered throughout the Torah, ensure the message cannot be ignored. The stranger's protection is woven into the fabric of Jewish law at multiple points, creating a safety net of overlapping obligations.

Rabbi Eliezer's insight transforms the convert's weakness into a theological principle. The Torah does not command extra protection for the powerful. It reserves its most emphatic and repeated commands for those who need them most. The frequency of the commandment is proportional to the vulnerability of the protected class.

Legends of the Jews 5:132Legends of the Jews

The story, as often happens, is richer and more nuanced than we might initially think.

The Torah tells us that thirteen years after Ishmael's birth, God commanded Abraham to perform brit milah, circumcision, making it a permanent sign of the covenant on their very bodies. But according to Ginzberg's retelling in Legends of the Jews, Abraham wasn't exactly thrilled about it at first. He worried that this physical mark would create a divide between him and the rest of humanity.

That: He's spent his life trying to bring people closer to the one God. Now, he's being asked to do something that might alienate them. But God reassures him, saying, "Let it suffice thee that I am thy God and thy Lord, as it sufficeth the world that I am its God and its Lord." In other words, trust in the divine plan, just as the world trusts in God's providence.

Still hesitant, Abraham does what any good leader would do: he seeks counsel. He turns to his three trusted friends: Aner, Eshcol, and Mamre. Now, it's interesting to note their responses. Aner's like, "Dude, you're almost a hundred years old! Are you sure you want to put yourself through that kind of pain?" Practical. Eshcol's concern is security. "You're going to mark yourself so your enemies can easily identify you?" A valid point in a turbulent world.

But then there's Mamre. He's the only one who urges obedience to God. He reminds Abraham of all the times God has saved him: from the fiery furnace, in his battles with kings, and during the famine. "God has always been there for you," he says, in essence. "Why hesitate now?"

It's fascinating, isn't it? The contrast between the practical concerns of Aner and Eshcol, and the unwavering faith of Mamre. It reflects the internal struggle Abraham himself must have been facing.

So, what does Abraham do? He listens to Mamre. He obeys God's command. But here's the kicker: he doesn't sneak off and do it in secret. According to Legends of the Jews, he does it in broad daylight, "bidding defiance to all, that none might say, 'Had we seen him attempt it, we should have prevented him.'" It wasn't just about following God's word. It was about making a public statement. A declaration of his unwavering faith. A challenge, perhaps, to those who doubted.

As we find in Midrash Rabbah, this act of defiance is characteristic of Abraham's commitment and courage. He’s not just passively accepting a command; he’s actively embracing it, showing the world that his dedication to God is unshakeable.

What does this story teach us? Perhaps it's about the importance of seeking wise counsel, but ultimately trusting in God's plan. Or maybe it's about the courage to stand up for what you believe in, even when it's difficult or unpopular. Or maybe, just maybe, it's a reminder that even our greatest forefathers wrestled with doubt and uncertainty, just like we do. And that's what makes their stories, and their faith, so enduring and so relatable, even today.
