Moshe went up to God, and the LORD called to him out of the mountain, saying, *This is what you shall tell the house of Ya`akov, and tell the children of Yisra'el:
All the people perceived the thunderings, the lightnings, the sound of the shofar, and the mountain smoking. When the people saw it, they trembled, and stayed at a distance.
Now Moshe was keeping the flock of Yitro, his father-in-law, the Kohen of Midyan, and he led the flock to the back of the wilderness, and came to God's mountain, to Chorev.
