חייך תלאים לך. עַל הַסָּפֵק, כָּל סָפֵק קָרוּי תָּלוּי, שֶׁמָּא אָמוּת הַיּוֹם בַּחֶרֶב הַבָּאָה עָלֵינוּ. וְרַבּוֹתֵינוּ דָרְשׁוּ זֶה הַלּוֹקֵחַ תְּבוּאָה מִן הַשּׁוּק: חייך תלאים לך THY LIFE SHALL HANG BEFORE THEE — because of uncertainty. — Anything that is uncertain may be termed תלוי (“hanging”); You will always be saying: “Perhaps I shall die to-day through the sword that is coming upon us”. — Our Rabbis interpreted this to refer to one who is obliged to buy produce in the market (who does not possess any of his own),

ולא תאמין בחייך. זֶה הַסּוֹמֵךְ עַל הַפַּלְטֵר (עי' מנחות ק"ג): ולא תאמין בחייך AND THOU SHALT HAVE NONE ASSURANCE OF THY LIFE — this they refer to one who must rely on the baker (cf. Menachot 103b).
