John Trapp on Psalms 109:8

Verſ. 8. Let his dayes be few] Let his execution be haſtened, as Hamans was. Ahitophel, and Judas were their own deaths-men. Doeg doubtleſs come to an ill end; and ſo did other perſecutors. See the book of Martyrs.

And let another take his office] Praefecturam. Officers are oft-times the Churches chiefeſt enemies; Popiſh Biſhops, eſpecially, as here in Q. Maries dayes. Judas was guide to thoſe that took Jeſus, Act. 1.16.20.
