In chapter XXXVI , I have said that it is not declared in what manner God spake supernaturally to Moses: nor that He spake not to him sometimes by dreams and visions, and by a supernatural voice, as to other prophets: for the manner how He spake unto him from the mercy-seat, is expressly set down ( Numb. 7:89) in these words: “From that time forward, when Moses entered into the tabernacle of the congregation to speak with God, he heard a voice which spake unto him from over the mercy-seat, which is over the ark of the testimony; from between the cherubims He spake unto him.” But it is not declared in what consisteth the preeminence of the manner of God’s speaking to Moses, above that of His speaking to other prophets, as to Samuel and to Abraham, to whom He also spake by a voice (that is, by vision), unless the difference consist in the clearness of the vision. For “face to face,” and “mouth to mouth,” cannot be literally understood of the infiniteness and incomprehensibility of the Divine nature.
