9 Let us then seek the testimonies to the Passion of Christ: for we are met together, not now to make a speculative exposition of the Scriptures, but rather to be certified of the things which we already believe. Now you have received from me first the testimonies concerning the coming of Jesus; and concerning His walking on the sea, for it is written, Your way is in the sea. Also concerning various cures you have on another occasion received testimony. Now therefore I begin from whence the Passion began.
Judas was the traitor, and he came against Him, and stood, speaking words of peace, but plotting war. Concerning him, therefore, the Psalmist says, My friends and My neighbours drew near against Me, and stood. And again, Their words were softer than oil, yet be they spears. Hail, Master; yet he was betraying his Master to death; he was not abashed at His warning, when He said, Judas, betrayest than the Son of Man with a kiss? For what He said to him was just this, Recollect your own name; Judas means confession; you have covenanted, you have received the money, make confession quickly. O God, pass not over My praise in silence; for the mouth of the wicked, and the mouth of the deceitful, are opened against Me; they have spoken against Me with a treacherous tongue, they have compassed Me about also with words of hatred. But that some of the chief-priests also were present, and that He was put in bonds before the gates of the city, you have heard before, if you remember the exposition of the Psalm, which has told the time and the place; how they returned at evening, and hungered like dogs, and encompassed the city.
