Holy Zohar text. Daily Zohar -345.

Tikkun 21 – 86

Isaiah 30:18 “כִּי-אֱלֹהֵי מִשְׁפָּט יְהוָה, אַשְׁרֵי כָּל-חוֹכֵי לוֹ”
“for YHVH is a God of justice, happy are all they that wait for Him.”

The Zohar references the word לוֹ, with numerical value of 36 to the righteous people that keep the world in existence.

There are 72 righteous people around the world. 36 in the land of Israel and 36 outside Israel. They serve as channels to the light of the Creator like the way God instructed Moses in the wilderness to assemble (in addition to him and Aaron), 70 elders that bestowed light from the same source as Moses received.
