New International Version

⁹ The Lord said to Moses, “I am going to come to you in a dense cloud,^(A) so that the people will hear me speaking^(B) with you and will always put their trust^(C) in you.” Then Moses told the Lord what the people had said.

¹⁰ And the Lord said to Moses, “Go to the people and consecrate^(D) them today and tomorrow. Have them wash their clothes^{(E) 11} and be ready by the third day,^(F) because on that day the Lord will come down^(G) on Mount Sinai^(H) in the sight of all the people.
