Let Christ the king of Israel
 Who sets up for the Messiah, and whose followers call him the king of Israel, whom the nation expected: and if he is so, let him 
 descend now from the cross, that we may see;
 see him come down, and be eyewitnesses of his power: 
 and believe;
 that he is the Messiah that was prophesied of, and has been waiting for: 
 and they that were crucified with him reviled him;
 that is, the thieves, at least one of them; (See Gill on Matthew 27:44).
