583. These four ER'ELIM stand to the four directions of the world, each standing watchful over Yisrael. They are called 'lattices', according to the verse, "He peers through the lattice" (Shir Hashirim 2:9), AND THE TWELVE ARE CALLED 'WINDOWS'. The names of the four lattices are Iga'el, Iriya, Ariel, Yehira'el. Iga'el stands to the east, looking after all those who do good deeds, and think righteous thoughts, though they are not able to perform.
586. Yehira'el stands to the west. He is in charge over those who are occupied in the Torah, and bring their sons to study Torah in school, and over those who look after the sick in their sickbed. They watch over them and tell them to examine their sins and deeds, and repent before their Master. For whoever looks after the sick, let him look after his deeds and repent before the Holy One, blessed be He, who will cause him to be saved, and his spirit to return to Him.
587. Concerning that, it is written, "Blessed is he who considers the poor: Hashem will deliver him in the day of evil" (Tehilim 41:2). HE ASKS: What is a day of evil? It should have been written, 'an evil day.' AND HE ANSWERS: A "day of evil" REFERS TO the day when evil has sway to take his soul. "Blessed is he who considers the poor (Heb. dal)." This refers to the sick, as it is written, "Why are you, being the king's son, so wasted (Heb. dal)" (II Shmuel 13:4). For that reason, "Hashem will deliver him in the day of evil," referring to those who look after the sick, and cause them to repent their sins before the Holy One, blessed be He as we explained. In this chamber stands THE ANGEL YEHIRA'EL watchful over him, so when Judgment dwells over the world, he will be saved. Therefore, "Hashem will deliver him in the day of evil," and on the day when Judgment is given in the hands of evil, THE ANGEL OF DEATH, to have power over him, "HASHEM WILL DELIVER HIM." All THE FOUR ER'ELIM are standing watchful, and therefore they are called 'lattices'.
593. In the same manner, the chieftain Yehira'el stands over all those who feel compassion for the poor, as said, "Blessed is he who considers the poor" (Ibid.). Hence everything is in this chamber. And this chamber is included within another, fourth chamber, where the decrees and Judgments of everyone are found. Happy is the portion of him, who knows the treasures of his Master, to be devoted to him and sanctify the Name of his Master always, so he may have merit in this world and in the World to Come.
