TT points to Tanna de-vei Eliyahu / parallel (R. Nehorai): Torah honors a person and protects him from all evil in his youth and gives him an end and hope in his old age — as with Avraham.
English of Core Text: It was taught: R. Nehorai says, the Torah honors a person and guards him from all evil in his youth and gives him an end and hope in his old age; so you find with Avraham our father… in his youth it says “Avram was very heavy…,” and in his old age “Avraham was old, coming into days, and Hashem blessed Avraham with everything.”
On the daf / in context: The derasha pairs the wealth of 13:2 with the later blessing of “bakol” to show Torah’s lifelong accompaniment of the one who keeps it.
