The “holy prophets” down to the time of Zedekiah may refer to the writings of Isaiah, Hosea, Amos, Micah, Nahum, Habakkuk, and Zephaniah, as well as Jeremiah.
Book of Mormon Central
Large sections of Isaiah appear throughout the Book of Mormon, Hosea 13:14 is alluded to in Mosiah 16:7–8, Moroni 7:32 quotes the Greek version of Amos 5:12, and Christ quoted Micah 5:8–9, and 4:12–13 in 3 Nephi 20:15–20 without introduction, suggesting that they already knew about the passage. Nahum, Habakkuk, and Zephaniah do not appear to be quoted in the Book of Mormon, but they were likely included in the plates of brass, as most scholars agree that these books were written before 600 BC. Jeremiah 17:5 is quoted in 2 Nephi 4:34. For more on when these Old Testament books were written, see Mordechai Cogan, “Into Exile: From the Assyrian Conquest of Israel to the Fall of Babylon,” in The Oxford History of the Biblical World, ed.
