The Shammah of Sabbath

The word that we tend to translate keep or observe. It's just Shammat, which is a watchman word. You have to, you have to guard Shabbat. The biblical God is the kills people, I guess. But although as Elle pointed out, this, like with Cain, this isn't God saying I will kill. It says they will certainly die,. Which actually I didn't look, I should have checked.
