Exodus 19:12-19 And you shall set bounds to the people round about, saying, Take heed to yourselves, that you go not up into the mount, or touch the border of it: whoever touches the mount shall be surely put to death:

AKJV⁽ⁱ⁾ ¹² And you shall set bounds to the people round about, saying, Take heed to yourselves, that you go not up into the mount, or touch the border of it: whoever touches the mount shall be surely put to death: ¹³ There shall not an hand touch it, but he shall surely be stoned, or shot through; whether it be beast or man, it shall not live: when the trumpet sounds long, they shall come up to the mount. ¹⁴ And Moses went down from the mount to the people, and sanctified the people; and they washed their clothes. ¹⁵ And he said to the people, Be ready against the third day: come not at your wives. ¹⁶ And it came to pass on the third day in the morning, that there were thunders and lightning, and a thick cloud on the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled. ¹⁷ And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount. ¹⁸ And mount Sinai was altogether on a smoke, because the LORD descended on it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly. ¹⁹ And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spoke, and God answered him by a voice.
