46. "And sets his heart upon it" (Devarim 24:15) refers to the Arvit service, which CORRESPONDS TO the parts of the sacrifice and the fatty parts that are left from the offerings of the day. They are like single grapes of the vineyard and "the corners of your field" (Vayikra 19:9) of which we learned that leaving things over in the form of charity hinders divine punishment. "You shall leave them for the poor and stranger" (Ibid. 10), THAT IS, TO THE CENTRAL PILLAR THAT IS ZEIR ANPIN. For the Central Pillar, when it is outside its place, NAMELY IN EXILE, is called a stranger. For that reason, THE FAITHFUL SHEPHERD SAID, I, my grade being of the Central Pillar, termed myself a stranger in the first exile. This is the meaning of, "I have been a stranger in a strange land" (Shemot 2:22), for he, ZEIR ANPIN, lies in exile for the sake OF YISRAEL.
