It is written in Exodus, The people saw the voice of the Lord. (Exod. 20:18.) Now a voice is rather heard than seen. But it was so written, to shew us that men see the voice of the Lord with other eyes, which they only have who are worthy of them. Again in the Gospel, it is not the voice that is perceived, but the Word, which is more excellent than the voice.
