Then Philip ran up to the chariot and heard the man reading Isaiah the prophet. “Do you understand what you are reading?” Philip asked.

“How can I,” he said, “unless someone explains it to me?” So he invited Philip to come up and sit with him.

This is the passage of Scripture the eunuch was reading:

“He was led like a sheep to the slaughter,
and as a lamb before its shearer is silent,
so he did not open his mouth.
In his humiliation he was deprived of justice.
Who can speak of his descendants?
For his life was taken from the earth.” (See Isaiah 53:7,8)

The eunuch asked Philip, “Tell me, please, who is the prophet talking about, himself or someone else?”

Then Philip began with that very passage of Scripture and told him the good news about Jesus.
