“רְאוּבֵן בְּכֹרִי אַתָּה, כֹּחִי וְרֵאשִׁית אוֹנִי–יֶתֶר שְׂאֵת, וְיֶתֶר עָז”
“Reuben, thou art my first-born, my might, and the first-fruits of my strength; more to carry, and more power.”
Cain was the firstborn and with that came a heavier burden of a Tikkun inherited from the parents. Adam followed the Snake and connected to Mortality. Cain needed to overcome the desire to bring death on his brother. He failed, like his father before him, to follow God’s advice and stay on the right path.
With the blessing of Jacob to his sons, Reuben recognized as the firstborn. He carried the strength and a greater responsibility for continuing the path of the father.
Cain was the first son of the first father and mother and Reuben was the first son of the first wife of Jacob. He started the line of the children of Israel, a name that was given to Jacob.
As the children of Israel, we carry the burden of the Tikkun of the world and have greater responsibility to continue the Light of the fathers to the entire world.
“כִּי-תִרְאֶה חֲמוֹר שֹׂנַאֲךָ, רֹבֵץ תַּחַת מַשָּׂאוֹ, וְחָדַלְתָּ, מֵעֲזֹב לוֹ–עָזֹב תַּעֲזֹב, עִמּוֹ”
“If you see the donkey of someone who hates you fallen down under its burden, do not leave him there; be sure you help him with it.”
The Zohar quotes this verse to teach us the responsibility for each other. When we see someone that we hate and he has difficulty following the ways of the Light and working on his Tikkun, then we should not ignore him and offer help in any way we can.
