The fourth section of the Book of Genesis continues the chronicle of Abraham. The name of this section (Vayeira, “He appeared”) is its first word, describing G‑d’s revelation to Abraham after his circumcision. This revelation is followed by the visit of three angels, who inform Abraham of his son Isaac’s imminent birth. We then follow Abraham as he argues with G‑d over the destruction of Sodom and Gomorrah, migrates to Philistia, banishes Hagar and Ishmael after Isaac is born, and is finally tested by G‑d’s directive to sacrifice Isaac.
