Jeremiah 17:21-23

Thus says the LORD: Take care for the sake of your lives, and do not bear a burden on the Sabbath day or bring it in by the gates of Jerusalem. And do not carry a burden out of your houses on the Sabbath or do any work, but keep the Sabbath day holy, as I commanded your fathers. Yet they did not listen or incline their ear, but stiffened their neck, that they might not hear and receive instruction.
