Nehemiah 13:19-22

19Then I commanded that the gates of Jerusalem should be shut as darkness fell every Friday evening, not to be opened until the Sabbath ended. I sent some of my own servants to guard the gates so that no merchandise could be brought in on the Sabbath day.

20The merchants and tradesmen with a variety of wares camped outside Jerusalem once or twice.

21But I spoke sharply to them and said, “What are you doing out here, camping around the wall? If you do this again, I will arrest you!” And that was the last time they came on the Sabbath.

22Then I commanded the Levites to purify themselves and to guard the gates in order to preserve the holiness of the Sabbath. Remember this good deed also, O my God! Have compassion on me according to your great and unfailing love.
