598. Why "the tenth part of an efah" (Bemidbar 28:5)? HE ANSWERS, the tenth part of an efah parallels the Congregation of Yisrael, which is the tenth grade, NAMELY MALCHUT, and it has to be placed between the two arms, WHICH ARE CHESED AND GVURAH OF ZEIR ANPIN, SO THAT IT SHOULD BE MADE UP OF CHOCHMAH OF THE LEFT AND CHASSADIM OF THE RIGHT. AND THEN it is fine flour for the baking of bread, and it is bread. And because MALCHUT is THE SECRET OF bread, no official in the world is appointed over bread made of the five kinds of grain, that are wheat, barley, rye, oats, and spelt, and no one is appointed over them, but the Holy One, blessed be He, alone.
599. And therefore poverty follows anyone who shows contempt to bread and throws it on the ground. And an angel that is appointed over this matter follows after him to assure him poverty. And he will not depart from this world until he has been in need of assistance from others. And it is written about such a one: "He wanders abroad for bread, saying, Where is it?" (Iyov 15:23), THE MEANING OF WHICH IS THAT HE shall wander abroad, going from place to place, IN HIS SEARCH for bread: 'Where is it?' And no one will have any regard for him, as it is written: "Where is it?" WHERE IS the one who will have mercy on him? For such a one will not be found.
600. Ra'aya Meheimna (the Faithful Shepherd). And in the first part, the Faithful Shepherd said: Whoever treats lightly crumbs of bread and throws them where they should not be, and even more so one who treats lightly pieces of marrow, that are drops of seed, and throws them on the ground, it is said about them: "for all flesh had corrupted its way upon the earth" (Beresheet 6:12). Or he who throws them to a menstruating woman, or the daughter of an idolater, or a bondwoman or a prostitute, and much more so one who treats lightly the crumbs of the bread of the Torah, which are THE SECRETS THAT ARE IN the tips of the letters and the crowns of the letters, about these it is said: He that makes worldly use of the crown shall perish.
601. And how much more so whoever transmits secrets of the Torah and the secrets of the Kabbalah and the secrets of the Works of Creation or secrets of the letters of the explicit Name to people who are not worthy, who are in the control of the Evil Inclination, a harlot, about whom it is written: "For by means of a harlot a man is brought to a piece of bread" (Mishlei 6:26). And whenever bread is mentioned the meaning is the 22 letters of the Torah, and whenever 'piece' is mentioned the meaning is even a single Halachah.
602. And in the first part, he revealed the secret of these crumbs, only according to the literal meaning, nor did he determine the amounts. But the sages of the Mishnah taught: The amount of the crumbs is not less than the size of an olive. And how much more so if they are of a quantity the size of an egg, for the sages of the Mishnah were stringent about them: How much should one eat to have to say the Blessing AFTER THE MEAL? An olive's size, an egg's size.
