Psalms 109:8 - Joseph Benson’s Commentary on the Old and New Testaments

Let his days be few The days of his life. Let him die an untimely death. So did Ahithophel, and so did Judas; both hanging themselves. And let another take his office Made void by his death. This is the clause which St. Peter has cited and applied to Judas, in his discourse to the disciples, at the election of Matthias into Judas's place. He cites, at the same time, a clause from Psalms 69:25; Let their habitation be desolate, and let no man dwell therein. This latter sentence, though in the plural number in the Hebrew, yet is applied by St. Peter in the singular number to Judas. The passage in this Psalm is singular, “yet applicable,” says Dr. Horne, “not to Judas only, but to the whole nation of the Jews; whose days, after they had crucified the Lord of glory, were few; who were dispossessed of the place and office which they held as the church of God, and to which, with all its honours and privileges, the Gentile Christian Church succeeded in their stead, when the Aaronical priesthood was abolished, and that of the true Melchisedek established for ever.”
