'Sabbath day' in the Bible

So says Jehovah, Take heed to yourselves, and carry no burden on the Sabbath day, nor bring it in by the gates of Jerusalem.

Nor carry out a burden from your houses on the Sabbath day, nor do any work, but keep the Sabbath day holy, as I commanded your fathers.

And it shall be, if you carefully listen to Me, says Jehovah, to bring in no burden through the gates of this city on the Sabbath day, but keep the Sabbath day holy, to do no work in it;

But if you will not listen to me to keep the Sabbath day holy, and not to carry a burden, even entering in at the gates of Jerusalem on the Sabbath day; then I will kindle a fire in its gates, and it will devour the palaces of Jerusalem, and it will not be put out.
