TT #3 · Parashas Mikeitz · First Aliyah · Passuk 41:14
וַיִּשְׁלַ֤ח פַּרְעֹה֙ וַיִּקְרָ֣א אֶת־יוֹסֵ֔ף וַיְרִיצֻ֖הוּ מִן־הַבּ֑וֹר וַיְגַלַּח֙ וַיְחַלֵּ֣ף שִׂמְלֹתָ֔יו וַיָּבֹ֖א אֶל־פַּרְעֹֽה׃
Then Pharaoh sent and called Yosef, and they brought him hastily out of the dungeon; and he shaved himself, and changed his raiment, and came in unto Pharaoh.
Torah Temimah points to Berachos 56b.
ת״ר, הרואה תגלחת בחלום ישכים ויאמר ויגלח ויחלף שמלותיו קודם שיקדמנו פסוק אחר (שופטים ט״ז:י״ז) אם גלחתי וסר ממני כחי.
English of Core Text: The Sages taught: One who sees a haircut in a dream should rise early and say “and he shaved himself and changed his raiment” before another verse [Judges 16:17] “If I be shaven, then my strength will go from me” can preempt it.
On the daf / in context: The Gemara lists positive and negative scriptural associations for various dream images and instructs the dreamer to seize the favorable verse first.
Type of Learning: Derash on the verse (Bavli sugya) — not a formal named middah of the 13; practical guidance drawn from the narrative of Yosef’s preparation to appear before Pharaoh.
What Is Learned: When a dream image can be linked to either a positive or a negative verse, one should immediately voice the positive verse so that the dream is directed toward good.
