At that time I saw people in Judah treading wine presses on the Sabbath. They were also bringing in stores of grain and loading [them] on donkeys, along with wine, grapes, and figs. All kinds of goods were being brought to Jerusalem on the Sabbath day. So I warned [them] against selling food on that day.
The Tyrians living there were importing fish and all kinds of merchandise and selling them on the Sabbath to the people of Judah in Jerusalem.
I rebuked the nobles of Judah and said to them: "What is this evil you are doing-profaning the Sabbath day?
Didn't your ancestors do the same, so that our God brought all this disaster on us and on this city? And now you are rekindling [His] anger against Israel by profaning the Sabbath!"
When shadows began to fall on the gates of Jerusalem just before the Sabbath, I gave orders that the gates be closed and not opened until after the Sabbath. I posted some of my men at the gates, so that no goods could enter during the Sabbath day.
Once or twice the merchants and those who sell all kinds of goods camped outside Jerusalem,
but I warned them, "Why are you camping in front of the wall? If you do it again, I'll use force against you." After that they did not come again on the Sabbath.
References for Nehemiah 13:21
Then I instructed the Levites to purify themselves and guard the gates in order to keep the Sabbath day holy. Remember me for this also, my God, and look on me with compassion in keeping with Your abundant, faithful love.
