Exodus 19:12-14

Amplified Bible

¹² You shall set barriers for the people all around [the mountain], saying, ‘Beware that you do not go up on the mountain or touch its border; whoever touches the mountain must be put to death. ¹³ No hand shall touch him [that is, no one shall try to save the guilty party], but the offender must be stoned or shot through [with arrows]; whether man or animal [that touches the mountain], he shall not live.’ When the ram’s horn sounds a long blast, they shall come up to the mountain.”^{(A) 14} So Moses went down from the mountain to the people and sanctified them [for God’s sacred purpose], and they washed their clothes.
