And ye said, behold, the Lord our God hath showed us his glory and his greatness,.... In descending on Mount Sinai in the manner he did, and giving the law from thence with such solemnity; for there was a glory in the ministration of it, as the apostle argues Co2 3:7, it being delivered with so much majesty, and such a glorious apparatus attending it; see Deu 33:2. Aben Ezra interprets this of the appearance of fire in which the Lord was, "and his greatness", of the thunders and lightnings, and the voice of the trumpet: and we have heard his voice out of the midst of the fire; the ten words, as the same interpreter rightly notes, which were vocally and audibly expressed out of the fire: we have seen this day, that God doth talk with man, and he liveth; they had proof of it in themselves; God had been talking with them out of the fire, and yet it did not reach and consume them, but they were still alive.
