“הַמְשַׁלֵּחַ מַעְיָנִים, בַּנְּחָלִים; בֵּין הָרִים, יְהַלֵּכוּן.”
“He sends forth springs in the valleys; They flow between the mountains;”
The ‘springs’ are Chokmah and Binah that come together to send the Light to the lower level. The ‘mountains’ is the aspect of patriarchs, Abraham, Isaac and Jacob for the Sefirot of Chessed, Gevurah and Tiferet.
“יַשְׁקוּ, כָּל-חַיְתוֹ שָׂדָי; יִשְׁבְּרוּ פְרָאִים צְמָאָם”
“They give drink to every living creature of the field; The wild quench their thirst.”
Everyone below Chokmah and Binah benefits from their unification.
The ‘wild’ are those who are in Malchut, and under the government of the Tree of Knowledge Good and Bad.
