Nehemiah 13:19

13:19 When the evening shadows began to fall on the gates of Jerusalem before the Sabbath, I ordered the doors to be closed. I further directed that they were not to be opened until after the Sabbath. I positioned some of my young men at the gates so that no load could enter on the Sabbath day.
