The name of the Parshah, "Vayera," means "And He appeared" and it is found in Genesis 18:1.

G‑d  reveals Himself to  Abraham three days after the first Jew’s  circumcision at  age ninety-nine; but Abraham rushes off to prepare a meal for three  guests who appear in the desert heat. One of the three—who are  angels disguised as men—announces that, in exactly one year, the barren Sarah will give birth to a son. Sarah laughs.

Abraham pleads with G‑d to spare the wicked city of  Sodom. Two of the three disguised angels arrive in the  doomed city, where Abraham’s nephew  Lot extends his hospitality to them and protects them from the evil intentions of a Sodomite mob. The two guests reveal that they have come to overturn the place, and to save Lot and his family. Lot’s wife  turns into a pillar of salt when she disobeys the command not to look back at the burning city as they flee.

While taking shelter in a cave, Lot’s two daughters (believing that they and their father are the only ones left alive in the world) get their father  drunk, lie with him and become pregnant. The two sons born from this incident father the nations of Moab and Ammon.

Abraham moves to Gerar, where the Philistine king Abimelech  takes Sarah—who is presented as Abraham’s sister—to his palace. In a dream, G‑d warns Abimelech that he will die unless he returns the woman to her husband. Abraham explains that he feared he would be killed over the beautiful Sarah.

G‑d remembers His promise to Sarah, and gives her and Abraham a son, who is named  Isaac (Yitzchak, meaning “will laugh”). Isaac is circumcised at the age of  eight days; Abraham is one hundred years old, and Sarah ninety, at their child’s birth.

Hagar and  Ishmael are  banished from Abraham’s home and wander in the desert; G‑d hears the cry of the dying lad, and saves his life by showing his mother a well. Abimelech makes a treaty with Abraham at Beersheba, where Abraham gives him  seven sheep as a sign of their truce.

G‑d tests Abraham’s devotion by  commanding him to sacrifice Isaac on Mount Moriah (the  Temple Mount) in Jerusalem. Isaac is  bound and placed on the altar, and  Abraham raises the knife to  slaughter his son. A voice from heaven calls to stop him; a ram, caught in the undergrowth by its horns, is offered in Isaac’s place.
