“And as they went on their way, they came unto a certain water: and the eunuch said, See, here is water; what doth hinder me to be baptized?”
King James Version (KJV)
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 8:36 They came unto a certain water. The locality of the baptism is not certain. There are several roads from Jerusalem to Gaza. The one by Hebron is through "desert" more than the others. Eusebius and Jerome state that the baptism occurred at a perennial stream, coming from a fountain at Bethsur, not far from Hebron. Robinson places the baptism not far from Gaza, at the old site of Eglon. See, [here is] water. The Greek is, "Behold! Water"! As if his soul was filled with joy that he could obey. What doth hinder me? Nothing, if he was a believer and the means were at hand.
