{A eunuch of great authority} (eunouchos dunast(8873)).
Eunuchs were often employed by oriental rulers in high posts.
_Dynasty_ comes from this old word dunast(8873) used of princes in
 Lu 1:52  and of God in  1Ti 6:15 . Eunuchs were not allowed to
be Jews in the full sense ( De 23:1 ), but only proselytes of the
gate. But Christianity is spreading to Samaritans and to eunuchs.
{Candace} (Kandak(8873)). Not a personal name, but like Pharaoh and
Ptolemy, the title of the queens of Ethiopia. This eunuch
apparently brought the gospel to Ethiopia. {Treasure} (gaz(8873)).
Persian word, common in late Greek and Latin for the royal
treasure, here only in the N.T. {For to worship} (proskun(8873)(936e)).
Future active participle expressing purpose, a common idiom in
the ancient Greek, but rare in the N.T. (Robertson, _Grammar_, p.
1128).
