Everyone knows the story of little Avraham and the big idol. And everyone knows where it is in the Torah.
Here is the story as presented in the Torah:
That is all we get for origin story of Avraham, before לך לך. So where does this aggadah come from? The key is clearly ויצאו אתם מאור כשדים ללכת ארצה כנען. They leave Ur, the capital of ancient Babylon, to head to the wild unknowns of כנען. They may not make it all the way there, and settle in חרן, before Avraham is called to complete the journey.
ה׳ will later remind Avraham about his “escape” from Ur:
So that is what we will focus on.
The previous perek gives us a peek into contemporary (to Avraham) politics:
Nimrod is the king of Babylon, as they are building the Tower that unites everyone into one fascist state: שפה אחת ודברים אחדים (we’ve talked about that extensively, most notably in פרשת נח תשע״ט). If you work out the chronology, Avraham is 48 at the time of the tower of Babel, presumably corresponding to his midrashic confrontation with Nimrod. So he is not a little kid at all. So what is Terach doing, bringing him before Nimrod? And in the פשט, why is Terach leaving Ur? There is an incredibly important Ramban that teaches us about the nature of aggadah, taking it seriously but not literally:
We know what Avraham’s mission in life was: preaching the message of ethical monotheism.
And that mission had started before he moved to כנען, when he was still living in חרן:
The implication of the way we are reading our parsha is that Avraham was preaching even during his days in Ur, and the powers that be tried to pull a Socrates and execute him for asebeia, “irreverence towards the state gods”. But ה׳ saves him, and he escapes to חרן. But it is his father Terach who brings him there: ויקח תרח את אברם בנו…ויצאו אתם מאור כשדים.
Rabbi Moshe Eisemann is bothered by a pasuk that we quote in the haggadah:
In this reading, Avraham learned the power of faith from Terach his father. And his father continues to support him, even as he goes into exile for his insane cult.
And I think that becomes an important lesson for our relationship with our children. No matter how much we disagree, how far off our דרך our children may go, we don’t need to cut off all contact. And no matter how wrong our parents may be, we still have much to learn from them. There’s a seemingly unimportant line in פרשת וירא:
After everything, after (בראשית יב:א) לך לך מארצך וממולדתך ומבית אביך, Avraham is still getting letters from his family. And that is the message of יקח תרח את אברם בנו.
