When Abraham was 86 years old, Sarah had not yet given him a son, so she told him to go to bed with her slave Hagar. Abraham's age was pluralistic, it was much more common to have multiple wives and have carnal relations with one's slaves. After their alliance, Hagar gave birth to Abraham's first son, Ishmael, whose name means God Hears. They lived together as a family until 13 years later, when God prophesied that Sarah would give birth to his son. Isaac's birth created a divide within their patchwork family, the two mothers disagreeing over their place in Abraham's family. Isaac, whose name means "Laughs," evokes Sarah's reaction when God told her she would have a son. When Isaac was born, Ishmael caused trouble by insulting and mocking him. Having had a son by his wife, Abraham was now more willing to rid himself of his first born son, Ishmael. Because Sarah realized that she would be a bad influence on Isaac, she proclaimed to Abraham: “Drive out this slave girl with her son; for the son of this slave will not be heir with my son Isaac." Abraham feared that throwing out his firstborn son would create an even worse situation; but God told Abraham to do as Sarah asked, and sent Hagar and Ishmael away with only food and water for their journey. During their journey, Hagar and Ishmael became lost in the wilderness of Beer Sheba and ran out of supplies. An angel approached them and said that God had seen Ishmael's suffering. The angel expressed that God had proclaimed that Ishmael would become the father of a great nation. God blessed Ishmael because he was the son of Abraham, and Ishmael's children became a great nation, known as the Ishmaelites, or the modern Arab people. When Abraham died years later, his… middle of paper… battle. During this war, Israeli forces conquered Sinai, Gaza, East Jerusalem, the West Bank, and the Golan Heights after Arab forces. These territorial advances gave Israel a buffer zone against its Arab neighbors and enemies. Then, in October 1973, the Yom Kippur War broke out, with loss of life on both sides but no change in Israel's borders. Then, in 1978, President Carter brought Egyptian and Israeli leaders together at Camp David. They discussed a treaty in which Egypt would regain full control of the Sinai Peninsula. As a result, the three nations signed the Camp David Accords on March 26, 1979; Egypt recognized the State of Israel and gave the world hope that one day there would be peace in the Middle East. Since the 1993 Oslo Accords, several summits and peace proposals have attempted to broker a broader peace plan, with limited success
