Dust and Earth and Pride

Non sic impii, non sic: sed tamquam pulvis quem proicit ventus a facie terrae. Terra hic accipienda est ipsa stabilitas in Deo, secundum quam dicitur: Dominus pars haereditatis meae, etenim haereditas mea praeclara est mihi; secundum hanc dicitur: Sustine Dominum, et observa vias eius, et exaltabit te, ut possideas terram; secundum hanc dicitur: Beati mites, quia ipsi haereditate possidebunt terram. Similitudo autem hinc ducta est; quia ut haec terra visibilis exteriorem hominem nutrit et continet, ita illa terra invisibilis interiorem hominem. A cuius terrae facie proicit ventus impium, id est superbia, quia inflat. Quam cavens ille qui inebriabatur ab ubertate domus Dei, et torrente voluptatis eius potabatur, dicit: Non veniat mihi pes superbiae. Ab hac terra proiecit superbia eum qui dixit: Ponam sedem meam ad Aquilonem, et ero similis Altissimo. Ab huius terrae facie proiecit etiam eum qui, cum consensisset et gustasset de prohibito ligno, ut esset sicut Deus, abscondit se a facie Dei. Hanc terram ad interiorem hominem pertinere, et inde superbia hominem proici, maxime intellegi potest in eo quod scriptum est: Quid superbit terra et cinis? quoniam in vita sua proiecit intima sua; unde enim proiectus est, non absurde se dicitur proiecisse. Sanctus Augustinus Hipponensi, Enarratio in Psalmum I

Not so the impious, not so, but they are like the dust which the wind blows forth from the face of the earth 1 The earth is here to be understood as that steadfastness in God, accordingly it is said, 'The Lord is the portion of my inheritance, mine is indeed a wondrous inheritance.'2 And on account of this it is said, 'Wait on the Lord and keep His ways, and He shall exalt you to inherit the earth.' 3 And on account of this it is said, 'Blessed are the meek, for they shall inherit the earth.' 4 A comparison also is drawn from this, for as this visible earth supports and contains the outer man, so does that invisible earth the inner man. From the face of that earth the wind blows forth the impious man, that is, the pride by which he is inflated. Which on guard against, he who was inebriated by the richness of the house of the Lord, and who drank of the rushing stream of its delights, says, 'Let not the foot of pride come against me.' 5 From this earth pride cast forth him who said, 'I will place my seat in the north, and I will be like the Most High.' 6 From the face of the earth it cast forth him also who, after he had consented and tasted of the forbidden tree that he might be as God, hid himself from the Face of God.7 That this earth pertains to the inner man, and that pride blows forth the man, may be especially understood in that which is written: 'Why is earth and ashes proud? Because in his life he cast forth his bowels.' 8 Because he cast forth, it is not unreasonably said that he has cast forth himself.
