What do we learn from "l'Mi Yoreh De'ah v'Es Mi Yavin Shemu'ah Gemulei me'Chalav Atikei mi'Shadayim"?
Sotah 12b: Moshe would not nurse from the Egyptian women. "To whom does He teach...? He who weaned himself from (impure) milk, who detached from the breast."
Avodah Zarah 3b: During the last three hours of the day, Hashem teaches children who died - "l'Mi Yoreh De'ah... Gemulei me'Chalav."
Rashi: To whom will one teach - to babies who cannot understand?! [He cannot teach] the adults, for they went on an evil path. Refer to 28:9:2:2-3.
Radak: Since they get drunk, and their entire involvement is eating and drinking and getting drunk, one who comes to teach them, to whom will he teach knowledge, and understanding of Shemu'ah (what the Navi heard from Hashem)? They have no intellect. They are like infants who sully themselves. They have no understanding to go to a special place to excrete.
Kli Paz: One who rebukes, he himself must be proper. Since the Kohen and Navi strayed, whom can they instruct [and not be told to fix themselves first]? Weaned babies?!
Malbim: Hashem says, after I rebuked them repeatedly via the Nevi'im, and they saw what happened to Efrayim, and they did not learn from a lesson, to whom will the Kohen teach knowledge, and to whom will the Navi inform the Nevu'ah that he heard? To weaned infants who do not understand the first time, and therefore one must teach to them 1000 times?!
Who are "Gemulei me'Chalav Atikei mi'Shadayim"?
Refer to 28:9:1:1-2.
Rashi #2: Gemulei me'Chalav are those who separated from their mothers'] milk. Atikei [refers to uprooting,] like "va'Ya'atek mi'Sham" (Bereishis 12:8).
Rashi #3: They separated from Torah, which is called milk. Atikei mi'Shadayim - they veered from [learning] in front of Chachamim.
Radak: They are infants who finished nursing, like "va'Yigdal ha'Yeled va'Yigamel" (Bereishis 21:8), "Ad Yigamel ha'Na'ar" (Shmuel I, 1:22). Then they begin to speak. They lack human understanding; their only difference from animals is speech.
