'Scripture' in the Bible

"Men [and] brothers, it was necessary [that] the scripture be fulfilled, which the Holy Spirit proclaimed beforehand through the mouth of David concerning Judas, who became a guide to those who arrested Jesus,

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

So Philip opened his mouth and beginning from this scripture, proclaimed the good news to him [about] Jesus.
