'Sabbath Day' in the Bible

And if the people of the land should bring wares or any provisions on the sabbath day to sell, that we would not buy it of them on the sabbath, or on the holy day: and that we would leave the seventh year, and the exaction of every debt.

In those days I saw in Judah some treading wine presses on the sabbath, and bringing in sheaves, and lading asses; as also wine, grapes, and figs, and all manner of burdens, which they brought into Jerusalem on the sabbath day: and I testified against them in the day in which they sold provisions.

Then I contended with the nobles of Judah, and said to them, What evil thing is this that ye do, and profane the sabbath day?

And it came to pass, that, when the gates of Jerusalem began to be dark before the sabbath, I commanded that the gates should be shut, and charged that they should not be opened till after the sabbath: and I set some of my servants at the gates, that there should no burden be brought in on the sabbath day.

And I commanded the Levites, that they should cleanse themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember me, O my God, concerning this also, and spare me according to the greatness of thy mercy.
