Exodus 19:13-15

Amplified Bible

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. ¹⁵ He said to the people, “Be prepared for the third day; do not ^[a]be intimate with a woman.”
