Isaac & Ishmael
God said to Abraham, "Look toward the heaven and number the stars and so shall your descendants be."
But Abraham's wife, Sarah, wasn't getting any younger, and God wasn't coming through on His promise. Anyway, Sarah was getting older, and she was getting nervous because she didn't have any children. So she sent Abraham to the bed of her maid, Hagar, and Abraham and Hagar had Ishmael. And not long after they did, God kept His promise to Sarah, as He'd always intended to, and Abraham and Sarah had Isaac. And Sarah said to Abraham, "Cast out this slave woman with her son, for the son of the slave woman will not be heir with my son Isaac."
And so it began: the Jews, the sons of Isaac. The Arabs, the sons of Ishmael.
But what most people find important to remember is that, in the end, the two sons came together to bury their father.
Love and forgiveness will take you farther than hate and anger.
