Exodus 19:16-18

  16 H7992 And it came to pass on the third H3117 day H1242 in the morning, H6963 that there were thunders H1300 and lightnings, H3515 and a thick H6051 cloud H2022 upon the mount, H6963 and the voice H7782 of the trumpet H3966 exceedingly H2389 loud; H5971 so that all the people H4264 that was in the camp H2729 trembled.
  17 H4872 And Moses H3318 brought forth H5971 the people H4264 out of the camp H7125 to meet H430 with God; H3320 and they stood H8482 at the lower H2022 part of the mount.
  18 H2022 And mount H5514 Sinai H6225 was altogether on a smoke, H6440 because H3068 the Lord H3381 descended H784 upon it in fire: H6227 and the smoke H5927 there ascended H6227 as the smoke H3536 of a furnace, H2022 and the whole mount H2729 quaked H3966 greatly.
