Nehemiah 13:19-22

19And it came to pass, that when the gates of Jerusalem began to be dark before the sabbath, I commanded that the gates should be shut, and charged that they should not be opened till after the sabbath: and I set some of my servants at the gates, that there should no burden be brought in on the sabbath day. 20So the merchants and sellers of all kind of wares lodged outside of Jerusalem once or twice. 21Then I testified against them, and said to them, Why lodge ye before the wall? if ye do so again, I will lay hands on you. From that time forth they came no more on the sabbath.1 22And I commanded the Levites that they should cleanse themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember me, O my God, concerning this also, and spare me according to the greatness of thy mercy.2
