EXTRA · Parashas Vayeishev · Passuk 39:8 · not a Torah Temimah citation on this passuk
But he refused. He said to his master’s wife, “Look, with me here, my master gives no thought to anything in this house, and all that he owns he has placed in my hands.
Classical source (EXTRA side-ring): Midrash Tanchuma Vayeishev 8.
Sefaria — Midrash Tanchuma Vayeishev 8
English: “And he refused” — this is what is said: “Blessed is the man who trusts in Hashem.”
Derash on the verse (Tanchuma) — not a formal named middah of the 13. Refusal is paired with the verse of trust in Hashem.
The strength to refuse is the practical form of bitachon — trust in Hashem rather than in circumstance.
