“Rabbi Yehuda said, ‘The tree from which Adam HaRishon ate was wheat, for the infant does not call out ‘Father and Mother’ before it tastes the taste of grain” (Sanhedrin 70b).
We should ask, 1) Since there are five kinds of grain, where is the proof that it is wheat? 2) If you say that we know that it is grain, meaning wheat, since precisely when the infant tastes the taste of wheat, it can call out “Father and Mother,” we must understand why specifically when it tastes the taste of wheat it knows, and when it tastes another kind, it does not know how to call out “Father and Mother.”
“Rabbi Yehuda said in the name of Rabbi Akiva, ‘Why did the Torah say, ‘Bring Omer [sheaf of wheat] on Passover? So that the crop in the fields will be blessed for you. And why did the Torah say ‘Bring two loaves of bread’ on Shavuot [Feast of Weeks]? It is because Shavuot is the time of the fruits of the tree.’ The Creator said, ‘Bring two loaves of bread before Me on Shavuot so that the fruits of the tree will be blessed for you’’” (Rosh Hashanah 16).
It is known that there are two degrees: There is a “field” that is “a field that the Lord has blessed,” and there is “a tree of the field.” Man is called “a tree of the field,” as it is written, “For man is a tree of the field.”
A “field” is called Malchut, a beast, Gematria BON, for the number of the name BON implies animal food. Hence, we offer a harvest of barley, which is animal food, for then Israel came out of Egypt, as it is said in The Zohar, that they came out from the authority of the Sitra Achra [other side]into the authority of Kedusha [holiness].
This is regarded as “I and not a messenger.” However, this is called “faith above reason,” when they still have not been rewarded with Torah, which is called “the quality of man,” regarded as “the view of Torah.”
This is what they were awarded on Shavuot at the time of the giving of the Torah, at which time man is called “a tree of the field.” Hence, at that time, wheat, which is man’s food, pertains to the sin of the tree of knowledge, which means that an infant does not call out “Father and Mother” before it tastes the taste of wheat.
The issue of “Father and Mother” pertains to the Mochin of Abba and Ima, which is the quality of Hochma and Bina, meaning Bina that returns to being Hochma.
