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 exceeding H2389 loud H5971 ; so that all the people H4264 that were in the camp H2729 [H8799] trembled.
  17 H4872 And Moses H3318 [H8686] brought forth H5971 the people H4264 out of the camp H7125 [H8800] to meet H430 with God H3320 [H8691] ; and they stood H8482 at the lower H2022 part of the mount.
  18 H2022 And mount H5514 Sinai H6225 [H8804] was altogether in a smoke H6440 H834 , because H3068 the LORD H3381 [H8804] descended H784 upon it in fire H6227 : and the smoke H5927 [H8799] of it ascended H6227 as the smoke H3536 of a furnace H2022 , and the whole mount H2729 [H8799] trembled H3966 greatly.
