Exodus 19:11-13 King James 2000 (KJ2000)

11. And be ready by the third day: for the third day the LORD will come down in the sight of all the people upon mount Sinai.

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

13. There shall not a 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.
