Gabriel’s name means “God is great,” and, as the angel of the annunciation, he is the one who revealed that the Savior was to be called “Jesus” (Luke 1:31). The first time we see Gabriel, he appears to Daniel after the prophet had a vision. Gabriel’s role is to explain the vision to Daniel (Daniel 8:16). More @Wikipedia
