Exodus 19:12-13 ▼

12 And you have made a border [for] the people all around, saying, Take heed to yourselves, going up into the mountain or coming against its extremity; whoever is coming against the mountain is certainly put to death;

13 a hand does not come against him, for he is certainly stoned or shot through, whether beast or man—it does not live; in the prolonging of the ram’s horn they go up into the mountain.”
