Jeremiah 17:22, 24, 27

Do not do your work on the Sabbath, but make it a holy day. I gave this command to your ancestors

“‘But if you obey me, says the LORD, and do not carry on your trade at the gates or work on the Sabbath day, and if you keep it holy

“‘But if you do not listen to me and refuse to keep the Sabbath holy, and if on the Sabbath day you bring loads of merchandise through the gates of Jerusalem just as on other days, then I will set fire to these gates. The fire will spread to the palaces, and no one will be able to put out the roaring flames.’”
