<p>23:7 <i>And when he knew that he was of Herod's jurisdiction, he sent him to Herod, who himself also was at Jerusalem in those days</i>- As noted on :6, this was a reflection of Pilate's desperate conscience. For it was his responsibility and not Herod's to deal with issues in Jerusalem, and it was down to him to authorize capital punishment and not Herod. So sending the Lord to Herod was a desperate attempt to get out of the situation.</p>
