13:21 And the Lord went before them in a pillar - In the two first stages, it was enough that God directed Moses whither to march; he knew the country, and the road; but now they are come to the edge of the wilderness, they would have occasion for a guide, and a very good guide they had, infinitely wise, kind, and faithful, the Lord went up before them; The Shechinah or appearance of the divine Majesty, which was a precious manifestation of the eternal Word, who in the fulness of time was to be made flesh, and dwell among us. Christ was with the church in the wilderness, 1Cor 10:9. What a satisfaction to Moses and the pious Israelites, to be sure that they were under a divine conduct? They need not fear missing their way who were thus led, nor being lost who were thus directed; they need not fear being benighted, who were thus illuminated, nor being robbed, who were thus protected. And they who make the glory of God their end, and the word of God their rule, the spirit of God the guide of their affections, and the providence of God the guide of their affairs, may be confident that the Lord goes before them, as truly is he went before Israel in the wilderness, though not so sensibly. They had sensible effects of God's going before them in this pillar. For, It led them the way in that vast howling wilderness, in which there was no road, no track, no way - marks through which they had no guides. When they marched, this pillar went before them, at the rate that they could follow, and appointed the place of their encampment, as infinite Wisdom saw fit; which eased them from care, and secured them from danger, both in moving, and in resting. It sheltered them from the heat by day, which at sometimes of the year was extreme: And it gave them light by night when they had occasion for it.

Letter xxxv. From Pope Damasus.
Damasus addresses five questions to Jerome with a request for information concerning them. They are: 1. What is the meaning of the words "Whosoever slayeth Cain vengeance shall be taken on him sevenfold"? (Gen. iv. 5.) 2. If God has made all things good, how comes it that He gives charge to Noah concerning unclean animals, and says to Peter, "What God hath cleansed that call not thou common"? (Acts x. 15.) 3. How is Gen. xv. 16, "in the fourth generation they shall come hither again," to be reconciled …

Epistle xxviii. To Augustine, Bishop of the Angli .
To Augustine, Bishop of the Angli [136] . Gregory to Augustine, &c. Glory to God in the highest, and on earth peace to men of good will (Luke ii. 14); because a grain of wheat, falling into the earth, has died, that it might not reign in heaven alone; even He by whose death we live, by whose weakness we are made strong, by whose suffering we are rescued from suffering, through whose love we seek in Britain for brethren whom we knew not, by whose gift we find those whom without knowing them we sought. …

Jesus Living at Nazareth and visiting Jerusalem in his Twelfth Year.
(Nazareth and Jerusalem, a.d. 7 or 8.) ^C Luke II. 40-52. ^c 40 And the child grew [This verse contains the history of thirty years. It describes the growth of our Lord as a natural, human growth (compare Luke i. 80); for, though Jesus was truly divine, he was also perfectly man. To try to distinguish between the divine and human in Jesus, is to waste time upon an impracticable mystery which is too subtle for our dull and finite minds], and waxed strong [His life expanded like other human lives. …
