Most people can do basic math.
Maybe not everybody can do linear algebra,
probability or calculus, but even relatively low-IQ palace servants living
1000 years before the birth of Christ could hardly fail to notice that
David’s latest wife, Bathsheba, had just delivered a baby well short of the
average human gestation period of forty weeks.
Sure, David married Bathsheba the moment he
could reasonably get away with it. But nobody was fooled. Their affair had to
be the worst-kept secret in Jerusalem.
