'Release' in the Bible

But ye have a custom, that I should release unto you one at the passover: will ye therefore that I release unto you the King of the Jews?

Then saith Pilate unto him, Speakest thou not unto me? knowest thou not that I have power to crucify thee, and have power to release thee?

And from thenceforth Pilate sought to release him: but the Jews cried out, saying, If thou let this man go, thou art not Caesar's friend: whosoever maketh himself a king speaketh against Caesar.
