Exodus 19:12-13 ▼

12 But you shall set boundaries for the people all around, saying, ‘Beware that you do not go up on the mountain or touch the border of it; whoever touches the mountain shall certainly be put to death.

13 No hand shall touch him, but he shall certainly be stoned or shot through; whether animal or person, the violator shall not live.’ When the ram’s horn sounds a long blast, they shall come up to the mountain.”
