John Gill Commentary Mark 15:9

"And Pilate answered them, saying, Will ye that I release unto you the King of the Jews?" — Mark 15:9 (ASV)

But Pilate answered them; saying Being satisfied of the innocence of Jesus, and being willing to dismiss him:

will you that I release unto you the king of the Jews ? he who is called so; and which he either said by way of derision both of Christ, and them; or else in order to prevail upon them to ask his release, it being scandalous and reproachful to put their king to death.
