In Parashat Bealotchah, when the people asked for meat Moses' reaction went eccentric (Num. 11:10):
מֵאַיִן לִי בָּשָׂר לָתֵת לְכָל־הָעָם הַזֶּה כִּי־יִבְכּוּ עָלַי לֵאמֹר תְּנָה־לָּנוּ בָשָׂר וְנֹאכֵלָה׃
לֹא־אוּכַל אָנֹכִי לְבַדִּי לָשֵׂאת אֶת־כָּל־הָעָם הַזֶּה כִּי כָבֵד מִמֶּנִּי׃
וְאִם־כָּכָה אַתְּ־עֹשֶׂה לִּי הָרְגֵנִי נָא הָרֹג אִם־מָצָאתִי חֵן בְּעֵינֶיךָ וְאַל־אֶרְאֶה בְּרָעָתִי
Where am I to get meat to give to all these people, when they whine before me and say, ‘Give us meat to eat!’
I cannot carry all these people by myself, for it is too much for me.
If You would deal thus with me, kill me rather, I beg You, and let me see no more of my wretchedness!”
Moses went through a lot of experiences with the Jewish people, in Egypt and beyond, inc. the Golden Calf. Here, the demand was, seemingly, simple - "ask G-d for some beef". Instead, he took it much personal (מֵאַיִן לִי בָּשָׂר לָתֵת) to the point he offers to be killed.
Previously he offered a similar solution to save the nation (מחני נא מספרך) but here I don't see how this solution will help the people here.
What made Moses so infuriated to the point of wanting to be killed?
