They that dwell in the wilderness shall bow before him; and his enemies shall lick the dust.
All Commentaries on Psalms 72:9 Go To Psalms 72
Augustine of Hippo
AD 430
12. "In His presence shall fall down the Ethiopians, and His enemies shall lick the earth" (ver. 9). By the Ethiopians, as by a part the whole, He hath signified all nations, selecting that nation to mention especially by name, which is at the ends of the earth. By "in His presence shall fall down" hath been signified, shall adore Him. And because there were to be schisms in divers quarters of the world, which would be jealous of the Church Catholic spread abroad in the whole round world, and again those same schisms dividing themselves into the names of men, and by loving the men under whose authority they had been rent, opposing themselves to the glory of Christ which is throughout all lands; so when He had said, "in His presence shall fall down the Ethiopians," He added, "and His enemies shall lick the earth:" that is, shall love men, so that they shall be jealous of the glory of Christ, to whom hath been said, "Be Thou exalted above the Heavens, O God, and above all the earth Thy glory." For man earned to hear, "Earth thou art, and unto earth thou shall go." By licking this earth, that is, being delighted with the vainly talking authority of such men, by loving them, and by counting them for the most pleasing of men, they gainsay the divine sayings, whereby the Catholic Church hath been foretold, not as to be in any particular quarter of the world, as certain schisms are, but in the whole universe by bearing fruit and growing so as to attain even unto the very Ethiopians, to wit, the remotest and foulest of mankind.
