Psalms 109:6

Set thou a wicked man over him,.... Or "them", as the Syriac version; over everyone of his adversaries, and all of them: and which may be interpreted, as it is by Cocceius, of tyrannical princes and governors, set over the Jews, as Tiberius, Caius, Claudius, Nero, c. and their deputies, Pilate, Felix, Festus, Florus all wicked men, and which were a judgment on them for their usage of Christ. Though here some single person is designed, even Judas, notorious for his enmity and ingratitude to Christ; and by the wicked one set over him may be meant Satan, as in the next clause, as he is sometimes called,

Matthew 13:38, into whose hands and power Judas was put, under whose influence he was; who entered into him, took possession of him, and put it into his heart to betray his Master, John 13:2.

And let Satan stand at his right hand; to direct and influence him, to solicit and tempt him to do the evil he did, and to accuse him for it when done; see Zechariah 3:1.
