Jews are the Children of Israel, i.e. Prophet Jacob, who primarily belonged to the area known as Juda. Israelites believe in all the prophets before Prophet Abraham, however the case becomes different when it comes till him. They believe that Prophet Abraham had one wife Sarah who gave birth to Isaac and one Egyptian handmaiden Hagar who gave birth to Ishmael. Hence from Prophet Abraham onwards their lineage became holy and chosen one for them as the prophets were coming from Prophet Isaac’s lineage down till them.
Jesus was sent upon the same people with the continuation of Mosas’ message.
