G-d speaks to Abram, commanding him to "Go from your land, from your birthplace and from your father's house, to the land which I will show you." There, G-d says, he will be made into a great nation. Abram and his wife Sarai, accompanied by his nephew Lot, journey to the Land of Canaan, where Abram builds an altar and continues to spread the message of a One G-d.
A famine forces the first Jew to depart for Egypt, where beautiful Sarai is taken to Pharaoh's palace; Abram escapes death because they present themselves as brother and sister. A plague prevents the Egyptian king from touching her and convinces him to return her to Abram and compensate the brother-revealed-as-husband with gold, silver and cattle.
Back in the Land of Canaan, Lot separates from Abram and settles in the evil city of Sodom, where he falls captive when the mighty armies of Chedorlaomer and his three allies conquer the five cities of the Sodom Valley. Abram sets out with a small band to rescue his nephew, defeats the four kings, and is blessed by Malki-Zedek the king of Salem (Jerusalem).
G-d seals the Covenant Between the Parts with Abram, in which the exile and persecution (Galut) of the people of Israel is foretold and the Holy Land is bequeathed to them as their eternal heritage.
Still childless ten years after their arrival in the Land, Sarai tells Abram to marry her maidservant Hagar. Hagar conceives, becomes insolent toward her mistress, and then flees when Sarai treats her harshly; an angel convinces her to return and tells her that her son will father a populous nation. Ishmael is born in Abram's 86th year.
Thirteen years later, G-d changes Abram's name to Abraham ("father of
multitudes") and Sarai's to Sarah ("princess"), and promises that a son will
be born to them; from this child, whom they should call Isaac ("will
laugh"), will stem the great nation with which G-d will establish His
special bond. Abraham is commanded to circumcise himself and his descendents
as a "sign of the covenant between Me and you."
