Nehemiah 13:19-22

When it began to be 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 set some of my servants over the gates, to prevent any burden from being brought in on the sabbath day. Then the merchants and sellers of all kinds of merchandise spent the night outside Jerusalem once or twice. But I warned them and said to them, “Why do you spend the night in front of the wall? If you do so again, I will lay hands on you.” From that time on they did not come on the sabbath. And 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.
