39, 40. the Spirit of the Lord caught away Philip--To deny [as MEYER, OLSHAUSEN, BLOOMFIELD] the miraculous nature of Philip's disappearance, is vain. It stands out on the face of the words, as just a repetition of what we read of the ancient prophets, in 1Ki 18:12; 2Ki 2:16. And the same word (as BENGEL remarks) is employed to express a similar idea in 2Co 12:2, 4; 1Th 4:17.
      the eunuch saw him no more--nor, perhaps, for very joy, cared to see him [BENGEL].
      and he went on his way rejoicing--He had found Christ, and the key to the Scriptures; his soul was set free, and his discipleship sealed; he had lost his teacher, but gained what was infinitely better: He felt himself a new man, and "his joy was full." Tradition says he was the first preacher of the Gospel in Ethiopia; and how, indeed, could he choose but "tell what the Lord had done for his soul?" Yet there is no certainty as to any historical connection between his labors and the introduction of Christianity into that country.
