EXTRA · Parashas Vayeishev · Passuk 37:25 · not a Torah Temimah citation on this passuk
Then they sat down to a meal. Looking up, they saw a caravan of Ishmaelites coming from Gilead, their camels bearing gum, balm, and ladanum to be taken to Egypt.
Classical source (EXTRA side-ring): Bereshis Rabbah 84:17.
Sefaria — Bereshis Rabbah 84:17
English: “And they lifted their eyes and saw, and behold, a caravan of Yishme’eilim” — the Holy One never strikes Yisrael unless He first creates a remedy for them.
Derash on the verse (Bereshis Rabbah) — not a formal named middah of the 13. Coincidence of the caravan is read as prior divine provision.
Even in the moment of betrayal, the caravan is already there as Yosef’s path of survival toward Mitzrayim.
