There are a few different ways to refer to the book of Zechariah in the Bible. One of the most common ways is simply to call it "Zechariah," as it is a standalone book within the Old Testament. Another option is to refer to it as a "prophetic book," as it is one of the prophetic texts in the Bible that contains messages from God for his people. Some people may also refer to it as a "minor prophet," as it is one of the shorter prophetic books in the Bible and is grouped with other shorter prophetic texts, such as Hosea, Joel, and Malachi.
