Isaac or Yitzchak (Hebrew: יִצְחָק, "he will laugh") was the only son of Abraham and Sarah, and the father of Jacob and Esau as described in the Hebrew Bible. His story is told in the Book of Genesis. Isaac was the longest-lived of the patriarchs, and the only biblical patriarch whose name was not changed. Isaac was the only patriarch who did not leave Canaan, although he once tried to leave and God told him not to do so. Compared to other patriarchs in the Bible, his story is less colorful, relating few incidents of his life.
The New Testament contains few references to Isaac. The early Christian church viewed Abraham's willingness to follow God's command to sacrifice Isaac as an example of faith and obedience.
Isaac is a prophet in Islam. A few narratives of Isaac appear in the Qur'an. The Qur'an views Isaac as a righteous man, servant of God and the father of Jews. The Qur'an states that Isaac and his progeny are blessed as long as they uphold their covenant with God. Some early Muslims believed that Isaac was the son who was supposed to be sacrificed by Abraham.
