Exodus 19:7-9

Young's Literal Translation

⁷ And Moses cometh, and calleth for the elders of the people, and setteth before them all these words which Jehovah hath commanded him;

⁸ and all the people answer together and say, `All that Jehovah hath spoken we do;' and Moses returneth the words of the people unto Jehovah.

⁹ And Jehovah saith unto Moses, `Lo, I am coming unto thee in the thickness of the cloud, so that the people hear in My speaking with thee, and also believe in thee to the age;' and Moses declareth the words of the people unto Jehovah.
