Acts 8:31

How can I? The question implies lack of ability, for he was not trained to interpret the Scriptures.

Guide. Greek hodeged, “to lead on one’s way,” “to guide.” The same word is used by Jesus of the guidance of the Holy Spirit (John 16:13). The eunuch, returning to Ethiopia, where he will be separated from those who have hitherto guided him in Jerusalem, feels that he needs skilled instruction for this difficult scripture. His question suggests that he is noticing the passage for the first time, or is having it pressed upon him by the Spirit with renewed emphasis.

Desired. Rather, “besought.” The word implies an earnest request, and indicates the eunuch’s eagerness to have more instruction. Note how smoothly the Spirit’s injunction (v. 29) is fulfilled. Philip draws near, and the eunuch himself invites the evangelist to enter his chariot and ride with him.
