The Prophet Jeremiah was a major figure in the Hebrew Bible, known for his role as a prophet during a turbulent time in ancient Israel. He lived in the late 7th and early 6th centuries BCE, witnessing the fall of Jerusalem and the destruction of the First Temple. His messages often focused on themes of repentance, social justice, and the consequences of turning away from God. Jeremiah is also known for his deep emotional struggles and personal laments, which are reflected in the book that bears his name. He is sometimes called the "weeping prophet" due to his sorrow over the fate of his people. His prophecies emphasized the need for a new covenant between God and the people of Israel.
