Acts 8:12-13, 16, 36-38

But when they believed Philip preaching good tidings concerning the kingdom of God and the name of Jesus Christ, they were baptized, both men and women. And Simon also himself believed: and being baptized, he continued with Philip; and beholding signs and great miracles wrought, he was amazed.

for as yet it was fallen upon none of them: only they had been baptized into the name of the Lord Jesus.

And as they went on the way, they came unto a certain water; and the eunuch saith, Behold, here is water; what doth hinder me to be baptized? And he commanded the chariot to stand still: and they both went down into the water, both Philip and the eunuch; and he baptized him.
