Page "Book of Zechariah" Paragraph 5

Some scholars accept the book as the writings of one individual.

For example, George Livingstone Robinson's dissertation on chapters 9-14 concluded that those chapters had their origin in the period between 518 and 516 BCE and stand in close relation to chapters 1-8, having most probably been composed by Zechariah himself.

However, most modern scholars believe the book of Zechariah was written by at least two different people.
