Exodus 19:13-15

King James Version

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.

¹⁴ And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.

¹⁵ And he said unto the people, Be ready against the third day: come not at your wives.
