La Genèse 49:14 Cabale : Zohar & Sha'arei Kedusha

The Holy One, blessed be He, outside His place is not a King. When He returns to His place, "Hashem shall be King" (Zechariah 14:9). It is said of Israel as well that all Israel are princes [Literally, 'the sons of kings']. Like the father, so are the sons. The children are not princes until they return to the land of Israel. You may say that he is a commoner, though he is a commoner in relation to his Master, do not treat lightly a blessing from a commoner, for this commoner is the servant Metatron. The first man, who did not keep the glory he was given [ because he ate from the Tree when he was not supposed to do so], was brought down to eat together with his donkey, and he said {to Hashem} 'I and my donkey shall eat from the same trough'. Issachar merited this donkey by being called, "Issachar is a strong donkey" (Genesis 49:14).

In contrast, a person who suffices with what is necessary for him is called a righteous Tzaddik, as scripture states,⁴⁷⁹Proverbs 13:25 “A righteous person eats to satisfy his soul.” Similarly, King David said,⁴⁸⁰Psalms 119:71 “It is good for me that I was afflicted, so that I might learn Your statutes.” We likewise find that our forefather Yaakov only requested the following,⁴⁸¹Genesis 28:20 “Give me bread to eat and clothes to wear.” It is likewise written,⁴⁸²Genesis 49:14 “Yissachar is a strong-boned donkey… he bent his shoulder to bear.”
