There are consequences for stubborn disobedience.
Read 2 Chronicles 36:17,18,21
So the Lord brought the king of Babylon against them. The Babylonians killed Judah’s young men, even chasing after them into the Temple. They had no pity on the people, killing both young men and young women, the old and the infirm. God handed all of them over to Nebuchadnezzar.
The king took home to Babylon all the articles, large and small, used in the Temple of God, and the treasures from both the Lord’s Temple and from the palace of the king and his officials.
So the message of the Lord spoken through Jeremiah was fulfilled. The land finally enjoyed its Sabbath rest, lying desolate until the seventy years were fulfilled, just as the prophet had said.
