Exodus 19:7-13

King James Version

⁷ And Moses came and called for the elders of the people, and laid before their faces all these words which the Lord commanded him.

⁸ And all the people answered together, and said, All that the Lord hath spoken we will do. And Moses returned the words of the people unto the Lord.

⁹ And the Lord said unto Moses, Lo, I come unto thee in a thick cloud, that the people may hear when I speak with thee, and believe thee for ever. And Moses told the words of the people unto the Lord.

¹⁰ And the Lord said unto Moses, Go unto the people, and sanctify them to day and to morrow, and let them wash their clothes,

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

¹² And thou shalt set bounds unto the people round about, saying, Take heed to yourselves, that ye go not up into the mount, or touch the border of it: whosoever toucheth 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 soundeth long, they shall come up to the mount.
