'Scripture' in the Bible

"Brothers, the scripture had to be fulfilled that the Holy Spirit foretold through David concerning Judas -- who became the guide for those who arrested Jesus --

Now the passage of scripture the man was reading was this: "He was led like a sheep to slaughter, and like a lamb before its shearer is silent, so he did not open his mouth.

So Philip started speaking, and beginning with this scripture proclaimed the good news about Jesus to him.
