'Sabbath Day' in the Bible

We will not buy on the Sabbath or on a holy day from the neighboring peoples who bring their wares and all kinds of grain to sell on the Sabbath day. We will let the fields lie fallow every seventh year, and we will cancel every loan.

In those days I saw people in Judah treading winepresses on the Sabbath, bringing in heaps of grain and loading them onto donkeys, along with wine, grapes, figs, and all kinds of loads, and bringing them to Jerusalem on the Sabbath day. So I warned them on the day that they sold these provisions.

So I registered a complaint with the nobles of Judah, saying to them, "What is this evil thing that you are doing, profaning the Sabbath day?

When the evening shadows began to fall on the gates of Jerusalem before the Sabbath, I ordered the doors to be closed. I further directed that they were not to be opened until after the Sabbath. I positioned some of my young men at the gates so that no load could enter on the Sabbath day.

Then I directed the Levites to purify themselves and come and guard the gates in order to keep the Sabbath day holy. For this please remember me, O my God, and have pity on me in keeping with your great love.
