Contradiction with Genesis 21:2
Genesis 18:11 states that Abraham and Sarah were old and Sarah was past the age of childbearing, yet Genesis 21:2 says Sarah bore a son despite this.
Genesis 21:2: For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
Contradiction with Hebrews 11:11
Genesis 18:11 suggests doubt due to old age, but Hebrews 11:11 states that through faith Sarah received strength to conceive.
Hebrews 11:11: Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised.
Paradox #1
Genesis 18:11 mentions that both Abraham and Sarah are old, and Sarah is past the age of childbearing. The potential contradiction arises from the biological perspective, as Sarah later gives birth to Isaac despite her advanced age, which is not typically possible according to natural human reproductive processes. This event is often viewed as a miraculous occurrence in religious texts.
Paradox #2
The contradiction in this context could be about the concept of age and childbirth. In Genesis 18:11, it is suggested that someone of an advanced age is having a child, which contradicts the scientific understanding that women have a limited fertile period, and natural conception becomes highly unlikely after menopause.
Paradox #3
Genesis 18:11 mentions that Sarah and Abraham are old and Sarah is past the age of childbearing. A potential contradiction or inconsistency could be seen when comparing this to later verses, specifically Genesis 21:2, where despite her old age, Sarah miraculously gives birth to Isaac. The conflict arises from the natural understanding of human biology and age, but the event is often viewed as a miracle.
