Smith's Bible Dictionary (1863)
a Jewish proselyte, (Acts 8:26) etc., who was treasurer of Candace queen of Ethiopia, but who was converted to Christianity on a visit to Jerusalem, through philip the evangelist. Nothing is known of him after his return to Ethiopia.
Hastings' Dictionary of the Bible (1898)
ETHIOPIAN EU'NUCH, THE, the Jewish proselyte who, returning from some feast in Jerusalem, was met by Philip the evangelist and baptized. Acts 8:26 ff. He was a eunuch in the strict sense, not in its official sense of "courtier," and the treasurer of Candace, queen of the Ethiopians. Candace was the name of a dynasty, and not of individual monarchs.
