Pirkei Avot 1.1: Moses received the Torah from Sinai and transmitted it to Joshua; Joshua to the elders; the elders to the prophets; and the prophets handed it down to the men of the Great Assembly. They said three things: Be deliberate in judgment, raise up many disciples, and make a fence around the Torah.
The transmission of Torah is like a bucket brigade: starting at Sinai, the Torah has been handed down, hand to hand, from that day to this. We call this the sharsheret shel masoret, the chain of tradition.
I learned to chant Torah from Cantor Ilene Keys at Temple Sinai in Oakland, CA. She learned from Cantor Nathan Lam at Stephen S. WIse Temple in Los Angeles. I don’t know who Cantor Lam learned from, but I know that the style of chanting we do is a variant of a style that goes all the way back to Eastern Europe.
Once, in the British Library in London, I saw a 9th century text of the Tanakh with the te’amim (cantillation marks – the musical notations) in it, and I was able to stand at the case where it was displayed and chant the text softly to myself. That codex was ancient — more than a thousand years old! — but I could read it just fine. That was the first time I really felt the weight of that chain of tradition. I could imagine the masorete who wrote that book teaching his student… and then the student teaching his student… down through the centuries until Cantor Lam taught Cantor Keys and Cantor Keys taught me.
The same is true of every d’var Torah — every word of Torah — that I know. Someone taught it to me, and I hand it along into the care of others.
A hundred years from now, I do not expect that many people, if any, will remember me. But I take great comfort and pride in the hope that the students of my students will still be learning Torah and handing it along to another generation, to continue the work of living Torah in the world. That is immortality.
