ויפתח האחד את שקו
And as one of them opened his sack to give his ass provender in the lodging-place, he saw his money; and, behold, it was in the mouth of his sack.
Bereishis Rabbah 91:9.
Sefaria · Bereishis Rabbah 91:9
וַיַּרְא אֶת כַּסְפּוֹ וְהִנֵּה הוּא בְּפִי אַמְתַּחְתּוֹ. הַגִּלּוּי בַּמָּלוֹן מַתְחִיל אֶת הַפַּחַד הַמְּשֻׁתָּף.
English of Core Text: Bereishis Rabbah 91:9 places the discovery of the money within its broader discussion of the brothers’ difficult return to Yaakov and his suspicion.
On the daf / in context: The midrash notes that the first sighting of the returned silver occurs away from home, forcing the brothers to confront the mystery together before they reach Yaakov.
Type of Learning: Derash on the verse (classic midrash) — not a formal named middah of the 13.
What Is Learned: The money reappears at the moment of ordinary need (feeding the animals); what was intended as a secret test becomes an open crisis on the road.
