Jeremiah 17:21-22

Thus says the LORD, “Pay attention for your own good, [and for the sake of your future] do not carry any load on the Sabbath day or bring anything in through the gates of Jerusalem. You shall not carry a load out of your houses on the Sabbath day nor do any work, but keep the Sabbath day holy [by setting it apart as a day of worship], as I commanded your fathers.
