English: “But you who cling to Hashem your God” — is it possible to cling to the Shechinah? Behold it is written “for Hashem your God is a consuming fire”! Rather, anyone who marries his daughter to a talmid chacham, or who does business for talmidei chachamim, or who benefits talmidei chachamim from his property — Scripture accounts it to him as if he clings to the Shechinah.
On the daf / in context: The Gemara resolves the paradox of devekus to a consuming fire by translating the mitzvah into concrete support of Torah scholars. Practical acts of enabling Torah study become the vehicle of attachment to Hashem.
Type of Learning
Custom (aggadic resolution of the impossibility of literal devekus).
What Is Learned
True clinging to Hashem is realized by supporting talmidei chachamim — marrying one’s daughter to them, conducting their business, or sustaining them from one’s property.
