Easton's 1897 Bible Dictionary:

Gabriel
   champion of God, used as a proper name to designate the angel
   who was sent to Daniel (8:16) to explain the vision of the ram
   and the he-goat, and to communicate the prediction of the
   seventy weeks (Dan. 9:21-27).

     He announced also the birth of John the Baptist (Luke 1:11),
   and of the Messiah (26). He describes himself in the words, "I
   am Gabriel, who stand in the presence of God" (1:19).
