Jeremiah is writing to people who were really in need of repentance. People whose lives were in ashes.
"You have been unfaithful to me," the Lord told them, "and I'm taking you back."
God made covenant with them. God had given them a home and they moved to Egypt. God brought them back home. They neglected God. They disobeyed God. They misused their gifts. They neglected neighbors in need. They were overrun by powerful enemies and taken into exile in Babylon. God renews the covenant and brings them back.
