Jeremiah is the Book of the Fall of Jerusalem. The weeping prophet was an eye-witness to the House of David being removed into captivity. Jeremiah was abused, afflicted, and agonized for his faithfulness to the LORD more than any other prophet in Jerusalem until Jesus Christ Himself.
The Hebrew, Greek, and English titles for the book are all taken from the proper name of the prophet who delivered the message of this book.
Jeremiah the son of Hilkiah, of the priests who were in Anathoth in the land of Benjamin is one of the most well-known Old Testament prophets. His Book is the most autobiographical of any prophetic writing. Linguistically yirmeyahuw could mean has exalted (to rise, lift up, exalt), or YHWH has thrown down (to cast, shoot, hurl, throw down).
