Abraham child Ishmael
Sarah
Thirteen years later, when Abram was 99 years of age, God declared Abram's new name: "Abraham" – "a father of many nations". Abraham then received the instructions for the covenant of the pieces, of which circumcision was to be the sign.God declared Sarai's new name: "Sarah", blessed her, and told Abraham, "I will give thee a son also of her". Abraham laughed, and "said in his heart, 'Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear [a child]?'" Immediately after Abraham's encounter with God, he had his entire household of men, including himself (age 99) and Ishmael (age 13), circumcised.Isaac
As had been prophesied in Mamre the previous year, Sarah became pregnant and bore a son to Abraham, on the first anniversary of the covenant of circumcision. Abraham was "an hundred years old", when his son whom he named Isaac was born; and he circumcised him when he was eight days old. For Sarah, the thought of giving birth and nursing a child, at such an old age, also brought her much laughter, as she declared, "God hath made me to laugh, so that all who hear will laugh with me." Isaac continued to grow and on the day he was weaned, Abraham held a great feast to honor the occasion. During the celebration, however, Sarah found Ishmael mocking; an observation that would begin to clarify the birthright of Isaac.
