Now therefore ye with the council signify to the chief captain that he bring him down unto you to morrow, as though ye would inquire something more perfectly concerning him: and we, or ever he come near, are ready to kill him.

And he said, The Jews have agreed to desire thee that thou wouldest bring down Paul to morrow into the council, as though they would inquire somewhat of him more perfectly.
