Which prophet is associated with both the 6th Century and the fall of Judah?

The prophet associated with both the 6th Century and the fall of Judah is Daniel. Daniel's prophecies take place during the Babylonian exile, which began after the fall of Jerusalem in 586 B.C. The Book of Daniel contains stories about his life in Babylon, as well as apocalyptic visions concerning future events that would affect not only Israel but also the surrounding nations. His experiences and prophecies are indicative of the historical context of the 6th Century, highlighting the themes of suffering, divine sovereignty, and hope for restoration.

The other prophets, while significant in their own right, either do not directly pertain to the events of the fall of Judah or their ministry occurs at different times. Haggai and Zechariah, for instance, prophesy after the return from exile, focusing on the rebuilding of the temple and encouraging the post-exilic community. Isaiah's ministry precedes the fall of Judah, dealing largely with issues leading up to the exile, rather than the events occurring during it. Thus, Daniel stands out as the prophet most relevant to both the timeframe and the circumstances surrounding the fall of Judah.
