TT · Parashas Mikeitz · Passuk 42:1
וַיַּ֣רְא יַעֲקֹ֔ב כִּ֥י יֶשׁ־שֶׁ֖בֶר בְּמִצְרָ֑יִם וַיֹּ֤אמֶר יַעֲקֹב֙ לְבָנָ֔יו לָ֖מָּה תִּתְרָאֽוּ׃
When Jacob saw that there were food rations to be had in Egypt, heahe Heb. “Jacob.” said to his sons, “Why do you keep looking at one another?
Torah Temimah points to classical midrashic sources on the language of the verse (see also Rashi and parallel discussions).
למה תתראו. אמר להם יעקב לבניו, אל תראו עצמכם כשאתם שבעים לא בפני עשו ולא בפני ישמעאל, כדי שלא יקנאו בכם.
English of Core Text: “Why do you look at one another?” Yaakov said to his sons: Do not make yourselves appear as if you are satiated — neither before Esav nor before Yishmael — so that they will not envy you.
On the daf / in context: The derash reads “titra’u” in the sense of appearing or displaying fullness, advising the brothers not to advertise their remaining stores of grain while famine gripped the surrounding peoples.
Type of Learning: Derash on the verse (midrashic / Bavli-style) — not a formal named middah of the 13; the teaching extracts practical counsel about avoiding the appearance of plenty in the presence of those who lack it.
What Is Learned: Even when one still has food, one should not display satiety before those who are hungry or potentially envious, lest it provoke jealousy and danger.
