22. These words the Lord spoke. That there may be no doubt about the authority of the law, and that it may not be depreciated by the people, Moses recalls to their memory that the presence of God, as He spoke it, was manifested by sure tokens; for this was the object of the fire, the clouds, and the darkness, whereby God’s voice was signalized, lest its source might be obscure. He adds, that it was “a great voice,” i.e., a voice which had, in an unwonted manner, penetrated far and wide. Nor are the witnesses few, whom he cites, but all that vast multitude, which for the most part would have been more disposed to extinguish the glory of God, unless it had been there made known by manifest proofs. The sum is, that there is no question as to who was the Lawgiver, whose majesty was then proclaimed by tremendous prodigies, and presented before the eyes of an immense multitude. It will be more convenient to speak elsewhere of the two tables. When Moses states that God “added no more,” he signifies that a perfect rule of life is contained in the ten commandments, and that, when their instruction is fully received, the whole body of wisdom is attained to, so that the people need seek to know no more; when God, then, made an end of speaking, he Himself laid down the bounds of legitimate inquiry.
