Contracted form of
Micaiah. Micah is one of the twelve minor prophets of the
Old Testament. He authored the Book of Micah, which alternates between prophesies of doom and prophesies of restoration. This is also the name of a separate person in the Book of Judges, the keeper of an idol. It was occasionally used as an English given name by the
Puritans after the
Protestant Reformation, but it did not become common until the end of the 20th century.
