Ezra 4 is the fourth chapter of the Book of Ezra in the Old Testament of the Christian Bible, or the book of Ezra-Nehemiah in the Hebrew Bible, which treats the book of Ezra and book of Nehemiah as one book. Jewish tradition states that Ezra is the author of Ezra-Nehemiah as well as the Book of Chronicles, but modern scholars generally accept that a compiler from the 5th century BCE (the so-called "Chronicler") is the final author of these books. The section comprising chapter 1 to 6 describes the history before the arrival of Ezra in the land of Judah in 468 BCE. This chapter records the opposition of the non-Jews to the re-building of the temple and their correspondence with the kings of Persia which brought a stop to the project until the reign of Darius the Great.
