Isaac is a patriarch in Genesis, the son of Abraham and Sarah and the father of Jacob and Esau. His story links the Abraham narratives with the later history of Jacob, whose name becomes Israel.
Birth and covenant
Genesis presents Isaac’s birth as the fulfillment of a promise made to Abraham and Sarah in their old age. The covenant promises of descendants and land are later renewed to Isaac, making him an important figure in the biblical ancestry of Israel.
The binding of Isaac
Genesis 22 tells how Abraham is commanded to offer Isaac, but the sacrifice is stopped and a ram is offered instead. In Jewish tradition the episode is known as the Akedah, or Binding of Isaac. Jewish and Christian interpreters have read the story in many ways, including as a test of Abraham, a reflection on obedience, and a major text in later theological interpretation.
Rebekah, Jacob, and Esau
Genesis 24 describes the search for Rebekah as Isaac’s wife. Their twin sons, Esau and Jacob, become central to the next generation of the narrative. Isaac favors Esau, while Rebekah favors Jacob. In Genesis 27, Jacob receives the blessing Isaac intended for Esau through a deception arranged with Rebekah.
Isaac in later religious traditions
Judaism remembers Isaac as one of the patriarchs Abraham, Isaac, and Jacob. Christianity also receives him through the Old Testament and refers to him in discussions of promise and faith. Islam honors Isaac (Ishaq) as a prophet and son of Abraham, although Islamic interpretation of Abraham’s near-sacrifice developed differently across sources and traditions.
Compared with Abraham and Jacob, Genesis gives Isaac fewer independent episodes. His importance lies largely in continuity: the covenantal family story passes through him to Jacob and the tribes of Israel.
