Nehemiah 13:19-22

19As soon as it began to grow dark at the gates of Jerusalem before the Sabbath, I commanded that the doors should be shut and gave orders that they should not be opened until after the Sabbath. And I stationed some of my servants at the gates, that no load might be brought in on the Sabbath day.

20Then the merchants and sellers of all kinds of wares lodged outside Jerusalem once or twice.

21But I warned them and said to them, "Why do you lodge outside the wall? If you do so again, I will lay hands on you." From that time on they did not come on the Sabbath.

22Then I commanded the Levites that they should purify themselves and come and guard the gates, to keep the Sabbath day holy. Remember this also in my favor, O my God, and spare me according to the greatness of your steadfast love.
