Numbers 21:5

באלהים ובמשה [AND THE PEOPLE SPAKE] AGAINST GOD AND AGAINST MOSES — They placed the servant on a par with his Master (Midrash Tanchuma, Chukat 19). למה העליתנו WHEREFORE HAVE YE BROUGHT US UP — “ye”: they (God and Moses) were both on a par to them. ונפשנו קצה AND OUR SOUL LOATHETH — This, too, is an expression for “the shortening of soul” and “rejecting” (not being able to bear the trouble). בלחם הקלקל THIS LIGHT BREAD — because the manna was miraculously absorbed into their limbs (and was not execrated) they derisively called it “light”. They said: this manna will at some time or other swell up in our stomachs, for is there any mortal (lit., anyone born of woman) who takes in food and does not eject it? (Yoma 75b; cf. Rashi on Avodah Zarah 5b).

וַיְדַבֵּ֣ר הָעָ֗ם בֵּֽאלֹהִים֮ וּבְמֹשֶׁה֒ לָמָ֤ה הֶֽעֱלִיתֻ֙נוּ֙ מִמִּצְרַ֔יִם לָמ֖וּת בַּמִּדְבָּ֑ר כִּ֣י אֵ֥ין לֶ֙חֶם֙ וְאֵ֣ין מַ֔יִם וְנַפְשֵׁ֣נוּ קָ֔צָה בַּלֶּ֖חֶם הַקְּלֹקֵֽל׃

And the people spoke against God, and against Moshe, Why have you brought us up out of Miżrayim to die in the wilderness? for there is no bread, nor is there any water; and our soul loathes this miserable bread.
