Exodus 19:10-12

Wycliffe Bible

¹⁰ which said to Moses (who said to Moses), Go thou (back) to the people, and make them holy today and tomorrow, and wash they their clothes,

¹¹ and be they ready into the third day; for in the third day the Lord shall come down before all the people on the hill of Sinai. (and be they ready by the third day; for on the third day the Lord shall come down on Mount Sinai in the sight of all the people.)

¹² And thou shalt set terms to the people, by compass; and thou shalt say to them, Be ye ware, that ye go not up into the hill, neither touch ye the ends thereof; each man that shall touch the hill, shall die by death. (And thou shalt set a boundary for the people, all around the mountain; and thou shalt say to them, Beware, that ye go not up onto the mountain, nor even touch its edges; for anyone who shall touch the mountain, shall die.)
