EXO 19:9

9 Then Yahweh said to Moses/me, “[Listen carefully]: I am going to appear to you from inside a thick cloud. When I am speaking to you, the people will hear it, and they will always trust in you.” Then Moses/I went [down the mountain and reported to the people what Yahweh said. Then he/I went back up the mountain and] told Yahweh what the people replied.
