Basil of Caesarea : The whole life of the saints and of the blessed, the example of the Lord himself while he was with us in the flesh, are aids to us in this matter. Moses, through long perseverance in fasting and prayer, received the law and heard the words of God, "as a man is inclined to speak to his friend." — THE LONG RULES 16 Jerome : [Daniel 2:22] "It is He who reveals deep and hidden things, and He knows what is placed in the darkness, and with Him is the light." A man to whom God makes profound revelations and who can say, "O the depth of the riches of the knowledge and wisdom of God!" (Romans 11:33), he it is who by the indwelling Spirit probes even into the deep things of God, and digs the deepest of wells in the depths of his soul. He is a man who has stirred up the whole earth, which is wont to conceal the deep waters, and he observes the command of God, saying: "Drink water from thy vessels and from the spring of thy wells" (Proverbs 5:15). As for the words which follow, "He knows what is placed in the darkness, and with Him is the light," the darkness signifies ignorance, and the light signifies knowledge and learning. Therefore as wrong cannot hide God away, so right encompasses and surrounds Him. Or else we should interpret the words to mean all the dark mysteries and deep things (concerning God), according to what we read in Proverbs: "He understands also the parable and the dark saying." (Proverbs 1:6, LXX) This in turn is equivalent to what we read in the Psalms: "Dark waters in the clouds of the sky" (Psalms 18:11). For one who ascends to the heights and forsakes the things of earth, and like the birds themselves seeks after the most rarified atmosphere and everything ethereal, he becomes like a cloud to which the truth of God penetrates and which habitually showers rain upon the saints. Replete with a plenitude of knowledge, he contains in his breast many dark waters enveloped with deep darkness, a darkness which only Moses can penetrate and speak with God face to face (Exodus 33:11), of Whom the Scripture says: "He hath made darkness His hiding-place" (Psalms 18:11). — St. Jerome, Commentary on Daniel, CHAPTER TWO Maximus of Turin : Fasting these forty days and nights holy Moses too merited to speak with God, to stand and stay with him and to receive the precepts of the law from his hand. For although this human condition prevented him from seeing God, yet the grace of his fasting drew him into close contact with the Divinity. For to fast frequently is a portion of God's virtues in ourselves, since God himself always fasts. He is more familiar, intimate and friendly with the person in whom he sees more of his works, as Scripture says: "And Moses spoke with God face to face like one speaking with his friend." — SERMON 35.3 Philoxenus of Mabbug : "But the young man Joshua departed not from the tent, but was there continually in the service of Moses;" and he that was free from going out and coming in among the multitude was especially nigh unto simplicity. If cunning and wickedness are gathered together from conversation with the multitude, it is evident that simplicity and integrity can be acquired from being brought up to lead a life of silent contemplation, and the more a man increaseth his life of contemplation, the more his possession of simplicity groweth. — 13 Ascetic Discourses, Discourse 4 -- On Faith: First Discourse on Simplicity
