'Keep the Sabbath' in the Bible

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.

But it will come about, if you listen diligently to Me,” says the Lord, “to bring no load in through the gates of this city on the Sabbath day, but keep the Sabbath day holy by doing no work on it,

But if you will not listen to Me and keep the Sabbath day holy by not carrying a load as you come in the gates of Jerusalem on the Sabbath day, then I will kindle a fire in her gates that cannot be extinguished, and it will devour the palaces of Jerusalem.”’”
