בְּאַרְבָּעָה פְרָקִים הָעוֹלָם נִדּוֹן, בְּפֶסַח עַל הַתְּבוּאָה, בַּעֲצֶרֶת עַל פֵּרוֹת הָאִילָן, בְּרֹאשׁ הַשָּׁנָה כָּל בָּאֵי הָעוֹלָם עוֹבְרִין לְפָנָיו כִּבְנֵי מָרוֹן, שֶׁנֶּאֱמַר (תהלים לג) הַיּוֹצֵר יַחַד לִבָּם, הַמֵּבִין אֶל כָּל מַעֲשֵׂיהֶם. וּבֶחָג נִדּוֹנִין עַל הַמָּיִם:
The world is judged in four periods: On Pesach, for produce [From the Torah's stating: Bring the omer before Me on Pesach so that I bless the grain in the fields for you, we derive that we are judged for produce on Pesach]; on Shevuoth, for the fruits of the trees [(This is derived) from the Torah's stating: Bring before Me the two breads on Shevuoth so that I bless the fruits of the trees for you. (The wheat plant is called a "tree," viz. (Genesis 2:17): "But from the tree of knowledge, good and evil, etc." This, according to the view that the tree from which Adam ate was a wheat plant.]; on Rosh Hashanah, all who have entered the world pass before Him as sheep, [which are made to pass through a narrow entrance to be tithed, two not being able to pass as one], viz. (Psalms 33:15): "He fashions their hearts as one; He considers all of their deeds." [The intent is: "The Fashioner sees their hearts all together and comprehends all of their deeds. For even though they pass before Him one by one, they are all "comprehended" in one "glance."]; and on Succoth, they are judged for water. [(This is derived from the Torah's stating: Pour water before Me on the festival (of Succoth)].
