I did a quick search in the "1881 Westcott-Hort New Testament" and found the following:
Chief Priest can be found in Matthew 2:4. The Greek word is Aρχιερεις
Archangel can be found in Jude 1:9. The Greek word is Αρχαγγελος
Here is some more info. on the 7 Archangels:
http://en.wikipedia.org/wiki/Seven_Archangels
The earliest reference to a system of seven archangels as a group appears to be in Enoch I (the Book of Enoch) which is not part of the Jewish Canon but is prevalent in the Judeo tradition, where they are named as Gabriel , Michael , Raphael , Uriel , Raguel , Remiel and Saraqael . While this book today is non-canonical in most Christian Churches, it was explicitly quoted in the New Testament ( Letter of Jude 1:14-15) and by many of the early Church Fathers . The Ethiopian Orthodox Church to this day regards it to be canonical .
