It's amazing to me how blind the high priests were not to see that Jesus was the Savior they had been waiting for. So many things that happened to him had been written about in scripture. (Matthew 27:1-10 is just one of many examples of this) The Message paraphrase ends this passage by saying,
"And so they unwittingly followed the divine instructions to the letter."
Matthew 27:10b (The Message)
Oh, that I won't be as blind as they were!
