Exodus 19:12-14

Expanded Bible

¹² But you must set a ·limit around the mountain that the people are not to cross [^Lboundary around the people]. ·Tell [Warn] them not to go up on the mountain and not to touch the ·foot [edge] of it. Anyone who touches the mountain must be put to death ¹³ with stones or shot with arrows. No one is allowed to touch him [^Ctouching a dead body rendered a person ritually unclean; Num. 5:2]. Whether it is a person or an animal, he will not live. But the ·trumpet [ram’s horn] will make a long blast, and only then may the people go up on the mountain.”

¹⁴ After Moses went down from the mountain to the people, he made them ·prepare themselves for service to God [consecrate/sanctify themselves], and they washed their clothes.
