'Sabbath Day' in the Bible

As for the peoples of the land who bring merchandise or any grain on the Sabbath day to sell, we will not buy from them on the Sabbath or on a holy day; and we will give up raising crops during the seventh year [leaving the land uncultivated], and forgive every debt.

In those days I saw some in Judah who were treading wine presses on the Sabbath, and bringing in sheaves or sacks of grain and loading them on donkeys, as well as wine, grapes, figs, and all kinds of loads, which they brought into Jerusalem on the Sabbath day. So I protested and warned them on the day they sold the produce.

Then I reprimanded the nobles of Judah, and said to them, “What is this evil thing that you are doing—profaning the Sabbath day?

Now when it began to get dark at the gates of Jerusalem before the Sabbath [began], I commanded that the doors be shut and not be opened until after the Sabbath. Then I stationed some of my servants at the gates so that no load [of merchandise] would enter [Jerusalem] on the Sabbath day.

And I commanded the Levites to purify themselves and come and guard the gates to keep the Sabbath day holy. O my God, remember me concerning this also and have compassion on me according to the greatness of Your lovingkindness.
