Exodus 19:18-20

MSTC(i) 18 And mount Sinai was altogether on a smoke: because the LORD descended down upon it in fire. And the smoke thereof ascended up, as it had been the smoke of a kiln, and all the mount was exceeding fearful. 19 And the voice of the horn blew and waxed louder, and louder. Moses spake, and God answered him and that with a voice. 20 And the LORD came down upon mount Sinai, even in the top of the hill, and called Moses up into the top of the hill. And Moses went up.
