Nehemiah 13:19-22

And it came to pass that, when the gates of Jerusalem began to be dark before the sabbath, I commanded that the doors should be shut, and commanded that they should not be opened till after the sabbath: and some of my servants set I over the gates, that there should no burden be brought in on the sabbath day. So the merchants and sellers of all kind of wares lodged without Jerusalem once or twice. Then I testified against them, and said unto them, Why lodge ye about the wall? if ye do so again, I will lay hands on you. From that time forth came they no more on the sabbath. And I commanded the Levites that they should purify themselves, and that they should come and keep the gates, to sanctify the sabbath day. Remember unto me, O my God, this also, and spare me according to the greatness of thy lovingkindness.
