Accoring to the Hebrew Bible, Isaac (Hebrew: Yitzchak יִצְחָק, Standard Yiẓḥaq Tiberian Yiṣḥāq ; Arabic: إسحٰق, ʾIsḥāq ; "he will laugh") is the son of Abraham and Sarah, and the father of Jacob and Esau. His story is told in the Book of Genesis. Abraham was 100 years old when Isaac was born. (Genesis 21:1-5) 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.
