Acts 8:30 (KJV)

And they, when they had testified and preached the word of the Lord, returned to Jerusalem, and preached the gospel in many villages of the Samaritans.

And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem unto Gaza, which is desert.

And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the charge of all her treasure, and had come to Jerusalem for to worship,

Was returning, and sitting in his chariot read Esaias the prophet.

Then the Spirit said unto Philip, Go near, and join thyself to this chariot.

And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.

The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:

In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth.

And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man?

Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.
