That your foot may be dipped in the blood of your enemies, and the tongue of your dogs in the same.
Read Chapter 68
Augustine of Hippo
28. "The Lord hath said, Out of Basan I will be turned" (ver. 22): or, as some copies have, "Out of Basan I will turn." For He turneth that we may be safe, of whom above hath been said, "God of our healths, and God of saving men." For to Him elsewhere also is said, "O God of virtues, turn Thou us, and show Thy face, and safe we shall be." Also in another place, "Turn us, O God of our healths." But he hath said, "Out of Basan I will turn." Basan is interpreted confusion. What is then, I will turn out of confusion, but that there is confounded because of his sins, he that is praying of the mercy of God that they may be put away? Thence it is that the Publican dared not even to lift up his eyes to Heaven: so, on considering himself, was he confounded; but he went down justified, because "the Lord hath said, Out of Basan I will turn." Basan is also interpreted drought: and rightly the Lord is understood to turn out of drought, that is, out of scarcity. For they that think themselves to be in plenty, though they be famished; and full, though they be altogether empty; are not turned. ..."I will turn unto the deep of the sea." If, "I will turn," why, "unto the deep of the sea"? Unto Himself indeed the Lord turneth, when savingly He turneth, and He is not surely Himself the deep of the sea. Doth perchance the Latin expression deceive us, and hath there been put "unto the deep," for a translation of what signifieth "deeply"? For He doth not turn Himself: but He turneth those that in the deep of this world lie sunk down with the weight of sins, in that place where one that is turned saith, "From the depths I have cried to Thee, O Lord." But if it is not, "I will turn," but, "I will be turned unto the deep of the sea;" our Lord is understood to have said, how by His own mercy He was turned even unto the deep of the sea, to deliver even those that were sinners in most desperate case. Though in one Greek copy I have found, not, "unto the deep," but "in the depths," that is, en buqoij: which strengtheneth the former sense, because even there God turneth to Himself men crying from the depths. And even if He be understood Himself there to be turned, to deliver such sort also, it is not beside the purpose: and so then He turneth, or else to deliver them is so turned, that His foot is stained in blood. Which to the Lord Himself the Prophet speaketh: "That Thy foot may be stained in blood" (ver. 23): that is, in order that they themselves who are turned to Thee, or to deliver whom Thou art turned, though in the deep of the sea by the burden of iniquity they may have been sunk, may make so great proficiency by Thy Grace (for where there hath abounded sin, there hath superabounded grace ), that they may become Thy foot among Thy members, to preach Thy Gospel, and for Thy name's sake drawing out a long martyrdom, even unto blood they may contend. For thus, as I judge, more meetly is perceived His foot stained in blood.
29. Lastly, he addeth, "The tongue of Thy dogs out of enemies by Himself," calling those very same that had been about to strive for the faith of the Gospel, even dogs, as though barking for their Lord. Not those dogs, whereof saith the Apostle, "Beware of dogs:" but those that eat of the crumbs which fall from the table of their masters. For having confessed this, the woman of Canaan merited to hear, "O woman, great is thy faith, be it done to thee as thou wilt." Dogs commendable, not abominable; observing fidelity towards their master, and before his house barking against enemies. Not only "of dogs" he hath said, but "of Thy dogs:" nor are their teeth praised, but their tongue is: for it was not indeed to no purpose, not without a great mystery, that Gedeon was bidden to lead those alone, who should lap the water of the river like dogs; and of such sort not more than three hundred among so great a multitude were found. In which number is the sign of the Cross because of the letter T, which in the Greek numeral characters signifieth three hundred. Of such dogs in another Psalm also said, "They shall be turned at even, and hunger they shall suffer as dogs." For even some dogs have been reproved by the Prophet Isaiah, not because they were dogs, but because they knew not how to bark, and loved to sleep. In which place indeed he hath shown, that if they had watched and barked for their Lord, they would have been praiseworthy dogs: just as they are praised, of whom is said, "The tongue of Thy dogs." ...
