Jacob ( /ˈdʒeɪkəb/; Hebrew: יַעֲקֹב‎‎ Standard Yaʿakov, Tiberian  Yaʿăqōḇ (help·info); Septuagint Greek: Ἰακώβ Iakōb; Arabic: يَعْقُوب‎ Yaʿqūb; "heel" or "leg-puller"), also later known as Israel (Hebrew: יִשְׂרָאֵל‎‎, Standard Yisraʾel, Tiberian Yiśrāʾēl; Septuagint Greek: Ἰσραήλ Israēl; Arabic: إِسْرَائِيل‎ Isrāʾīl; "persevere with God"), as described in the Hebrew Bible, the Talmud, the New Testament and the Qur'an was the third patriarch of the Hebrew people with whom God made a covenant, and ancestor of the tribes of Israel, which were named after his descendants.

In the Hebrew Bible, he is the son of Isaac and Rebekah, the grandson of Abraham and Sarah and of Bethuel, and the younger twin brother of Esau. Jacob had twelve sons and at least one daughter, by his two wives, Leah and Rachel, and by their female slaves Bilhah and Zilpah. The children named in Genesis were Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, daughter Dinah, Joseph, and Benjamin.

Before the birth of Benjamin, Jacob is renamed "Israel" by an angel (Genesis 32:28-29 and 35:10). The name "Israel" can be translated as "God contended", but other meanings have also been suggested. Some commentators say the name comes from the verb śœarar ("to rule, be strong, have authority over"), thereby making the name mean "God rules" or "God judges". Other possible meanings include "the prince of God" (from the King James Version) or "El fights/struggles".
