Midrash sur L’Exode 16:3

"in the desert": We are hereby taught that he rebuked them for what they did in the desert. They took their small sons and daughters and threw them into Moses' lap and said to him? What provisions did you make for these? What livelihood did you provide for them? R. Yehudah says: This ("in the desert") refers to (Shemoth 16:3) "And the children of Israel said to them (Moses and Aaron): Would that we had died by the hand of the L-rd in the land of Egypt!"

Rabbi Levi said: Any place where [the phrase] “the hand of God” is stated, it is the plague of pestilence. The paradigm of them all is: “Behold, the hand of the Lord is [upon your cattle… a very severe pestilence]” (Exodus 9:3). Bar Kappara said: They demanded with the hand,¹¹⁴“Would that we had died by the hand of God in Egypt” (Exodus 16:3). and the hand¹¹⁵Regarding the generation of the wilderness, it is written: “And the hand of God was against them…until their demise” (Deuteronomy 2:14–15). harmed them. Rabbi Simon said: Among those who departed [the land of Israel] there was a plague;¹¹⁶This is derived from the fact that it states here: “The hand of the Lord has emerged against me [yatze’a bi],” which can be interpreted in the sense of biyatzi, “when I left.” among those who remained there was no plague. The students of Rabbi Neḥemya cite it from there: This is what is written: “Wherever they departed, the hand of the Lord was against them for evil” (Judges 2:15) – among those who departed there was a plague; among those who remained there was no plague. Rabbi Reuven said: Their children,¹¹⁷The children of those who departed Egypt. too, were suffering in their wake, and saying: ‘When will they die so we can enter the Land?’
