Exodus 19:12-13

BSB(i) 12 And you are to set up a boundary for the people around the mountain and tell them, ‘Be careful not to go up on the mountain or touch its base. Whoever touches the mountain shall surely be put to death. 13 No hand shall touch him, but he shall surely be stoned or shot with arrows—whether man or beast, he must not live.’ Only when the ram’s horn sounds a long blast may they approach the mountain.”
