“And the eunuch answering Philip, said: I beseech thee, of whom doth the prophet speak this? of himself, or of some other man?”
“And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man? That he should at all know either that the Prophets speak in different ways about different persons, or that they speak of themselves in another person-the question betokens a very thoughtful mind.”
“"I ask you to tell me, of whom does the prophet say this?" To know that the prophets sometimes speak about others as well, or about themselves in another person, because this is what his question shows — the quality of a very observant man.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
