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.
585. Ariel stands to the north. He is watchful over those who planned to do evil, but did not, or wanted to sin, but when they came to commit TRANSGRESSION, they overcame their inclination and abstained from doing it.
