Isaac

Isaac is the son born to Abraham and Sarah in their old age; his name means "he laughs." In Genesis 22 God tells Abraham to offer Isaac as a sacrifice on a mountain in the land of Moriah. At the last moment an angel stops him and a ram is offered instead. This episode, the Akedah or binding of Isaac, is central in Jewish, Christian and Islamic thought, though Islamic tradition often names Ishmael as the son.

Isaac marries Rebekah and fathers the twins Esau and Jacob. He is the only patriarch who never leaves Canaan and whose name is never changed, and Genesis says he lived 180 years.

The Book of Jubilees retells the binding in a way that echoes the opening of Job: Prince Mastema, the leader of evil spirits, suggests the test to God. This is one of several places where Jubilees gives troubling acts in Genesis to Mastema. Isaac is known from Genesis and later interpretation.
