Parashas Toldos · Passuk 25:34
Yaakov then gave Esav bread and lentil stew; he ate and drank, and he rose and went away. Thus did Esav despise the birthright.
Rashi on Bereishis 25:34 (classical source on this passuk; not listed as a numbered Torah Temimah unit here).
Lemma / focus: ויבז עשו.
English: Scripture testifies to his wickedness: that he despised the service of the Omnipresent.
Derash on the verse (Rashi) — not a formal named middah of the 13: “despised the birthright” is read as despising the divine service itself.
Esav ate, drank, rose, and went; Scripture testifies that he despised the birthright—and with it the service of Hashem.
