Yaakov, also called Yisrael, is the second-born son of Yitzhak and Rivka, the third of Israel's patriarchs: Avraham, Yitzhak and Yaakov. When Esav is born, Yaakov, still in the womb, holds fast to Esav's heel (akev) which is the source of Yaakov's name. Unlike his active brother, Yaakov is a homebody preferring "dwelling in tents" to running in the fields. One day, Yaakov is in the process of cooking a stew when Esav returns from the hunt. Yaakov agrees to feed his brother in return for the rights that Esav holds as oldest son.
