Now an angel of the Lord said to Philip, "Get up and go south to the desert road that goes down from Jerusalem to Gaza." So he started out, and on his way he met an Ethiopian eunuch, a court official in charge of the entire treasury of Candace, queen of the Ethiopians. He had gone to Jerusalem to worship, and on his return was sitting in his chariot reading Isaiah the prophet. The Spirit said to Philip, "Go over to that chariot and stay by it." So Philip ran up and heard the man reading Isaiah the prophet. "Do you understand what you are reading?" Philip asked. "How can I," he said, "unless someone guides me?" And he invited Philip to come up and sit with him. The eunuch was reading this passage of Scripture: "He was led like a sheep to the slaughter, and as a lamb before the shearer is silent, so He did not open His mouth. In His humiliation He was deprived of justice. Who can recount His descendants? For His life was removed from the earth." "Tell me," said the eunuch, "who is the prophet talking about, himself or someone else?" Then Philip began with this very Scripture and told him the good news about Jesus. As they traveled along the road and came to some water, the eunuch said, "Look, here is water! What is there to prevent me from being baptized?" And he gave orders to stop the chariot. Then both Philip and the eunuch went down into the water, and Philip baptized him. When they came up out of the water, the Spirit of the Lord carried Philip away, and the eunuch saw him no more, but went on his way rejoicing. But Philip appeared at Azotus and traveled through that region, preaching the gospel in all the towns until he came to Caesarea.
Let no foreigner who has joined himself to the LORD say, "The LORD will utterly exclude me from His people." And let the eunuch not say, "I am but a dry tree." For this is what the LORD says: "To the eunuchs who keep My Sabbaths, who choose what pleases Me and hold fast to My covenant— I will give them, in My house and within My walls, a memorial and a name better than that of sons and daughters. I will give them an everlasting name that will not be cut off. And the foreigners who join themselves to the LORD to minister to Him, to love the name of the LORD, and to be His servants—all who keep the Sabbath without profaning it and who hold fast to My covenant— I will bring them to My holy mountain and make them joyful in My house of prayer. Their burnt offerings and sacrifices will be accepted on My altar, for My house will be called a house of prayer for all the nations." Thus declares the Lord GOD, who gathers the dispersed of Israel: "I will gather to them still others besides those already gathered."
Significance
The Ethiopian eunuch episode in Acts 8:26-40 enacts the specific promise of Isa 56:3-8 with extraordinary precision. Isaiah 56 addresses two groups excluded from the Mosaic assembly: eunuchs (Deut 23:1) and foreigners, and promises both full inclusion in the new covenant community. The Ethiopian man is both — a eunuch (Acts 8:27) from Ethiopia/Cush, a nation representing the distant Gentile world (cf. Isa 18:1; Zeph 3:10). Moreover, he had traveled to Jerusalem to worship (Acts 8:27), precisely as Isa 56:6-7 anticipates foreigners who "join themselves to the LORD to minister to Him and to love the name of the LORD... these I will bring to My holy mountain." The specific passage he is reading (Isa 53:7-8) comes from the same Isaiah scroll that contains Isa 56, and Philip's exposition leads to baptism — the sign of inclusion. Luke's narrative signals that Isa 56's promise of the eunuch who "is not a dry tree" (56:3) is fulfilled in this man's reception of the life-giving Spirit.
