 Unto the end, a psalm for David.  O God, be not thou silent in my praise: for the mouth of the wicked and the mouth of the deceitful man is opened against me.  They have spoken against me with deceitful tongues; and they have compassed me about with words of hatred; and have fought against me without cause.  Instead of making me a return of love, they detracted me: but I gave myself to prayer.  And they repaid me evil for good: and hatred for my love.
 Set thou the sinner over him: and may the devil stand at his right hand.  When he is judged, may he go out condemned; and may his prayer be turned to sin.  May his days be few: and his bishopric let another take.  May his children be fatherless, and his wife a widow.  Let his children be carried about vagabonds, and beg; and let them be cast out of their dwellings.
Saint Augustine wrote of this passage:
Set thou an ungodly man to be ruler over him; and let Satan stand at his right hand Psalm 108:5. Though the complaint had been before concerning many, the Psalm is now speaking of one….Since therefore he is here speaking of the traitor Judas, who, according to the Scripture in the Acts of the Apostles, was to be punished with the penalty due to him, Acts 1:20 what means,
set thou an ungodly man over him, save him whom in the next verse he mentions by name, when he says,
and let Satan stand at his right hand? He therefore who refused to be subject unto Christ, deserved this, that he should have the devil set over him, that is, that he should be subject unto the devil….For this reason also it is said of those who, preferring the pleasures of this world to God, styled the people blessed who have such and such things,
their right hand is a right hand of iniquity.. ..
9. Psalm 108:6. For prayer is not righteous except through Christ, whom he sold in his atrocious sin: but the prayer which is not made through Christ, not only cannot blot out sin, but is itself turned into sin. But it may be inquired on what occasion Judas could have so prayed, that his prayer was turned into sin. I suppose that before he betrayed the Lord, while he was thinking of betraying Him; for he could no longer pray through Christ. For after he betrayed Him, and repented of it, if he prayed through Christ, he would ask for pardon; if he asked for pardon, he would have hope; if he had hope, he would hope for mercy; if he hoped for mercy, he would not have hanged himself in despair….
Let his days be few Psalm 108:7. By
his days, he meant the days of his apostleship, which were few; since before the Passion of our Lord, they were ended by his crime and death. And as if it were asked, What then shall become of that most sacred number twelve, within which our Lord willed, not without a meaning, to limit His twelve first Apostles? He at once adds,
and let another take his office. As much as to say, let both himself be punished according to his desert, and let his number be filled up.
