Nehemiah 13:19-22

19And it came to pass, that when it began to be dark in the gates of Jerusalem before the sabbath, I commanded that the gates should be shut; and I commanded that they should not be opened till after the sabbath. And I set [some] of my servants at the gates, so that no burden should be brought in on the sabbath day.

20And the dealers and sellers of all kind of ware passed the night without Jerusalem once or twice.

21And I testified against them, and said to them, Why do ye pass the night before the wall? if ye do so again, I will lay hands on you. From that time forth they came not on the sabbath.

22And I commanded the Levites that they should purify themselves, and that they should come and keep the gates, to hallow the sabbath day. Remember this also for me, my 1God, and spare me according to thy great loving-kindness!
