'On the Sabbath' in the Bible

This is what the Lord has said: See to yourselves, that you take up no weight on the Sabbath day, or take it in through the doors of Jerusalem;

And take no weight out of your houses on the Sabbath day, or do any work, but keep the Sabbath day holy, as I gave orders to your fathers;

And it will be, that if with all care you give ear to me, says the Lord, and take no weight through the doorways of this town on the Sabbath day, but keep the Sabbath day holy and do no work in it;

But if you do not give ear to me, to keep the Sabbath day holy, and to let no weight be lifted and taken through the doors of Jerusalem on the Sabbath day: then I will put a fire in its doorways, burning up the great houses of Jerusalem, and it will never be put out.
