That He is the righteous One whom the Jews should put to death
In the Wisdom of Solomon: “Let us lay hold of the righteous, because He is disagreeable to us, and is contrary to our works, and reproaches us with our transgressions of the law. He professes that He has the knowledge of God, and calls Himself the Son of God; He has become to us an exposure of our thoughts; He is grievous unto us even to look upon, because His life is unlike to others, and His ways are changed. We are esteemed by Him as frivolous, and He restrains Himself from our ways, as if from uncleanness; and He extols the last end of the righteous, and boasts that He has God for His Father.
Let us see, then, if His words are true, and let us try what will come to Him. Let us interrogate Him with reproach and torture, that we may know His reverence and prove His patience. Let us condemn Him with a most shameful death. These things they considered, and erred. For their maliciousness has blinded them, and they knew not the sacraments of God.” Also in Isaiah: “See how the righteous perishes, and no man understands; and righteous men are taken away, and no man regards.
For the righteous man is taken away from the face of unrighteousness, and his burial shall be in peace.” Concerning this very thing it was before foretold in Exodus: “You shall not slay the innocent and the righteous.” Also in the Gospel: “Judas, led by penitence, said to the priests and elders, I have sinned, in that I have betrayed the innocent blood.”
