Vulnerability in Pesach
(יא) וְכָכָה֮ תֹּאכְל֣וּ אֹתוֹ֒ מָתְנֵיכֶ֣ם חֲגֻרִ֔ים נַֽעֲלֵיכֶם֙ בְּרַגְלֵיכֶ֔ם וּמַקֶּלְכֶ֖ם בְּיֶדְכֶ֑ם וַאֲכַלְתֶּ֤ם אֹתוֹ֙ בְּחִפָּז֔וֹן פֶּ֥סַח ה֖וּא לַיהוָֽה׃
(11) This is how you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it hurriedly: it is a passover offering to the LORD.

(ב) דָּבָר אַחֵר, שְׁלָחַיִךְ פַּרְדֵּס רִמּוֹנִים, דָּמְיָה לְפַרְדֵּס רִמּוֹנִים, לִישָׁן בְּנֵי נַשׁ הוּא מַה שָּׁלַח פְּלוֹנִי לַאֲרוּסָתֵיהּ, רִמּוֹנִים. רַבִּי חֲנִינָא וְרַבִּי סִימוֹן, חַד אָמַר הִיא הִכְנִיסָה לוֹ שְׁלשׁ עֶשְׂרֵה, וְהוּא הִכְנִיס לָהּ שְׁלשׁ עֶשְׂרֵה. הִיא הִכְנִיסָה לוֹ שְׁלשׁ עֶשְׂרֵה...

The well of [Miriam]. Where did the Israelites procure wine for drink-offerings all forty years that they spent in the wilderness? Rabbi Yochanan said: from the well. From it came most of their enjoyments, for Rabbi Yochanan said: the well used to produce for them various kinds of herbs, of vegetables and of trees. The proof for this is when Miriam died and the well ceased to give its waters to them….

שאלו תלמידיו את רבי שמעון בן יוחי מפני מה לא ירד להם לישראל מן פעם אחת בשנה אמר להם אמשול לכם משל למה הדבר דומה למלך בשר ודם שיש לו בן אחד פסק לו מזונותיו פעם אחת בשנה ולא היה מקביל פני אביו אלא פעם אחת בשנה עמד ופסק מזונותיו בכל יום והיה מקביל פני אביו כל יום
Furthermore, with regard to the manna: The students of Rabbi Shimon ben Yoḥai asked him: Why didn’t the manna fall for the Jewish people just once a year to take care of all their needs, instead of coming down every day? He said to them: I will give you a parable: To what does this matter compare? To a king of flesh and blood who has only one son. He granted him an allowance for food once a year and the son greeted his father only once a year, when it was time for him to receive his allowance. So he arose and granted him his food every day, and his son visited him every day.
אף ישראל מי שיש לו ארבעה וחמשה בנים היה דואג ואומר שמא לא ירד מן למחר ונמצאו כולן מתים ברעב נמצאו כולן מכוונים את לבם לאביהן שבשמים
So too, in the case of the Jewish people, someone who had four or five children would be worried and say: Perhaps the manna will not fall tomorrow and we will all die of starvation. Consequently, everyone directed their hearts to their Father in heaven every day. The manna that fell each day was sufficient only for that day, so that all of the Jewish people would pray to God for food for the next day.
