Luke 23:18

And they cried out all at once
The chief priests, rulers, and people, not bearing to hear of a release of him, now they had got him in their hands; and enraged at the proposal, in a most clamorous way, cried out, as one man, immediately:

Saying, away with this man;
to the cross; to Calvary, the place of execution; away with him out of the world; he is not fit to live:

and release unto us Barabbas;
whose character is given in the next verse; (See Gill on Matthew 27:16).
