“Then Philip opened his mouth, and began at the same scripture, and preached unto him Jesus.”
King James Version (KJV)
8:33 In his humiliation his judgment was taken away - That is, when he was a man, he had no justice shown him. To take away a person's judgment, is a proverbial phrase for oppressing him. And who shall declare, or count his generation - That is, who can number his seed, #Isa 53:10|; which he hath purchased by laying down his life?
8:36 And as they went on the way they came to a certain water - Thus, even the circumstances of the journey were under the direction of God. The kingdom of God suits itself to external circumstances, without any violence, as air yields to all bodies, and yet pervades all. What hindereth me to be baptized? - Probably he had been circumcised: otherwise Cornelius would not have been the first fruits of the Gentiles.
Ac 8:35 Then Philip . . . preached unto him Jesus. He showed the prophecies of the Messiah, that it behooved him to suffer, die, and rise again, and that he commanded his gospel to be preached and believers to be baptized in his name. That the eunuch calls for baptism (Ac 8:36) shows that in preaching Jesus, Philip preached the rite.
