Albert Barnes Commentary John 19:6

"When therefore the chief priests and the officers saw him, they cried out, saying, Crucify [him], crucify [him]! Pilate saith unto them, Take him yourselves, and crucify him: for I find no crime in him." — John 19:6 (ASV)

They cried out, saying, Crucify him, and so on. The view of the Savior's meekness only exasperated them further. They had resolved on his death; and as they saw Pilate disposed to acquit him, they redoubled their cries and endeavored to gain by tumult, clamor, and terror what they saw they could not obtain by justice.

When people are determined on evil, they cannot be reasoned with. Every argument tends to defeat their plans, and they press on in iniquity with an earnestness that increases as sound reasons are urged to halt their progress. Thus, sinners go in the way of wickedness down to death. They make up in firmness of purpose what they lack in reason. They become all the more fixed in their plans as God faithfully warns them and their friends admonish them.

Take ye him, and so on. These are evidently the words of a man weary of their insistence and with the subject, and yet resolved not to sanction their conduct. It was not the act of a judge delivering him up according to the forms of the law, for they did not understand it so. It was equivalent to this:

"I am satisfied of his innocence, and shall not
pronounce the sentence of death. If you are bent
on his ruin—if you are determined to put to death an
innocent man—if my judgment does not satisfy you—take
him and put him to death on your own responsibility,
and take the consequences. It cannot be done with
my consent, nor in the due form of law; and if done,
it must be by you, without authority, and in the face
of justice."

See Matthew 27:24.
