Many years before, Sarah had an Egyptian woman that worked for her. Her name was Hagar. When Sarah found that she could not have a baby, she gave Hagar to be like a wife for Abraham. Sarah did this so that Hagar and Abraham could have a baby together. Hagar did have a son and Abraham named him Ishmael. Later on, Abraham sent Hagar and Ishmael away from his camp. But God had promised Hagar that Ishmael would have a big family.
