Parashas Toldos · Passuk 26:13
And the man grew richer and richer until he was very wealthy.
Rashi on Bereishis 26:13 / Bereshit Rabbah (classical source on this passuk; not listed as a numbered Torah Temimah unit here).
Lemma / focus: כי גדל מאד.
English: People used to say: Better the dung of Yitzchak’s mules than the silver and gold of Avimelech.
Derash on the verse (Rashi / midrash) — not a formal named middah of the 13: “very great” is illustrated by a popular saying about relative wealth.
Yitzchak grew very great; people said the dung of his mules was worth more than Avimelech’s silver and gold.
