This is a trivia question for those who have never been to Israel.
There isn’t any bodies of water between Gaza and Jerusalem. So where did Philip baptize the eunuch?
Act 8:26 But an angel of the Lord spoke to Philip saying, "Get up and go south
to the road that descends from Jerusalem to Gaza." (This is a desert road.)
Act 8:36 As they went along the road they came to some water; and the eunuch *said, "Look! Water! What prevents me from being baptized?"
Act 8:37 [And Philip said, "If you believe with all your heart, you may." And he answered and said, "I believe that Jesus Christ is the Son of God."]
Act 8:38 And he ordered the chariot to stop;
and they both went down into the water, Philip as well as the eunuch, and he baptized him.
