Kabbalah for Numbers 22:6
וְעַתָּה֩ לְכָה־נָּ֨א אָֽרָה־לִּ֜י אֶת־הָעָ֣ם הַזֶּ֗ה כִּֽי־עָצ֥וּם הוּא֙ מִמֶּ֔נִּי אוּלַ֤י אוּכַל֙ נַכֶּה־בּ֔וֹ וַאֲגָרְשֶׁ֖נּוּ מִן־הָאָ֑רֶץ כִּ֣י יָדַ֗עְתִּי אֵ֤ת אֲשֶׁר־תְּבָרֵךְ֙ מְבֹרָ֔ךְ וַאֲשֶׁ֥ר תָּאֹ֖ר יוּאָֽר׃
Come now therefore, I pray thee, curse me this people; for they are too mighty for me; peradventure I shall prevail, that we may smite them, and that I may drive them out of the land; for I know that he whom thou blessest is blessed, and he whom thou cursest is cursed.’
Zohar
Rabbi Abba said, Everyone was aware that Laban was the best at sorcery and wizardry, and he could use sorcery to do away with anyone he wished. All that Bilaam knew came from Laban. Regarding Bilaam, it is written, "for I know that he whom you bless is blessed, and he whom you curse is cursed" (Num. 22:6). Because everyone feared Laban and his sorcery, the first words that Jacob sent Esau were, "I have sojourned with Laban." In case Esau thought it was for a short period, perhaps a month or a year, Jacob advised, "and stayed there until now" twenty years did I stay with him.
