TSK · Exodus 19:21

God said,“Do not approach any closer! Take your sandals off your feet, for the place where you are standing is holy ground.”

But he added,“You cannot see my face, for no one can see me and live.”

“Do not allow the tribe of the families of the Kohathites to be cut off from among the Levites;

But the Kohathites are not to go in to watch while the holy things are being covered, or they will die.”

Rash Vows(4:17) Be careful what you do when you go to the temple of God; draw near to listen rather than to offer a sacrifice like fools, for they do not realize that they are doing wrong.
