NEH 13:19

19 So I ordered that at ◄the beginning of every Sabbath day/every Friday evening► they should shut the gates of the city before it became dark. I also ordered that they should not open the gates until ◄the Sabbath day was ended [the next day]/Saturday evening►. Then [each Sabbath day] I put some of my men at the gates, so they would make sure that nothing to sell was brought into the city on that day.
