“Since, therefore, all things are seen and heard, let us fear him and abandon the abominable lusts that spawn evil works, in order that we may be shielded by his mercy from the coming judgments. For where can any of us escape from his mighty hand? For the Scripture says somewhere, "Where shall I go, and where shall I be hidden from your presence? If I ascend to heaven, you are there; if I depart to the ends of the earth, there is your right hand; if I take my bed in the depths, there is your Spirit." Where, then, can one go, or where can one flee from him who embraces the universe?”

“My mind, intent on the study of truth, took delight in these most pious teachings about God. For it did not consider any other thing worthy of God than that he is so far beyond the power of comprehension that the more the infinite spirit would endeavor to encompass him to any degree, even though it be by an arbitrary assumption, the more the infinity of a measureless eternity would surpass the entire infinity of the nature that pursues it. Although we understood this teaching in a reverent manner, it was clearly confirmed by these words of the prophet: "Whither shall I go from your spirit? Or whither shall I flee from your face? If I ascend into heaven, you are there; if I descend into hell, you are present. If I take my wings early in the morning and dwell in the uttermost parts of the sea, even there also shall your hand lead me and your right hand shall hold me." There is no place without God, nor is there any place which is not in God. He is in heaven, in hell and beyond the seas. He is within all things; he comes forth and is outside all things. While he thus possesses and is possessed, he is not included in anything nor is he not in all things.”

“This plan he found: So will I flee, saith he, from Thy Face, so will I flee from Thy Spirit; from Thy avenging Spirit, Thy avenging Face thus will I flee. How? "If I take again my wings right forward, and abide in the utmost parts of the sea" [Psalm 139:9]. So can I flee from Thy Face. If he will flee to the utmost part of the sea from the Face of God, will not He from whom he fleeth be there? ...For what are "the utmost parts of the sea," but the end of the world? Thither let us now flee in hope and longing, with the wings of twofold love; let us have no rest, save in "the utmost parts of the sea." For if elsewhere we wish for rest, we shall be hurled headlong into the sea. Let us fly even to the ends of the sea, let us bear ourselves aloft on the wings of twofold love; meanwhile let us flee to God in hope, and in faithful hope let us meditate on that "end of the sea."”

“For Deity alone is uncircumscribed, existing everywhere, and as the same and in the same manner. For if I ascend, saith David, into heaven, thou art there; if I descend into Hades thou art present there; if I should take to myself wings at morning—that is, in the east—and dwell in the uttermost parts of the sea—that is, in the west—even there shall thy hand lead me: evidently indicating here the uncircumscribed nature of the Deity”

“[If] I take up the wings of dawn If I take up for myself the wings of dawn, which shine at once from one end of the world to the other, so will I fly swiftly until I dwell at the end of the sea.”

“Even there shall thy hand lead me,.... For he could not get there with all the assistance of the wings of the morning, could they be had, without the leadings of divine Providence; and when there, being a good man, should experience the leadings of divine grace; let the people of God be where they will, he heads them as a parent his child, teaching him to go; and as a shepherd his flock, into green pastures, and to fountains of living water; he leads to himself, and to his Son by his Spirit; into communion and fellowship with them, and to a participation of all blessings grace; guides them with his counsel, and directs all their ways and going; and thy right hand shall hold me; the Lord lays hold on his people, and apprehends them for himself, and claims his interest in them; he holds them in his ways, that they slip and fall not; he upholds them with the right hand of his righteousness, and they are safe; and he holds them from going into or on in wrong ways to their hurt.”

“In the morning. Shachar is so rendered by St. Jerome. (Haydock) — Some would understand “the black eagle,” (Lyranus) or the east, (Origen) or aurora. The poets assign wings to the sun, &c., Malachias iv. 2. (Calmet)”
