Gabriel means 'mighty man of God' or 'God is my strong man,' from geber (mighty man) and El (God). He appears in Daniel (8:16; 9:21) as the angel sent to help Daniel understand visions. In the New Testament, Gabriel announces the births of John the Baptist (Luke 1:19) and Jesus (Luke 1:26-38). He is one of only two named angels in canonical Scripture (the other being Michael).
Gabriel is the angel of divine announcement — the messenger of God's redemptive plan. His appearances mark turning points in salvation history: Daniel's vision of the 70 weeks (Daniel 9:24-27) and the Annunciation to Mary (Luke 1:30-33). The name itself is theological: God sends His 'mighty man' to deliver His most important messages. Gabriel standing in God's presence (Luke 1:19) indicates a high rank. His ministry shows that God communicates His purposes through messengers — ultimately fulfilled in the incarnate Word.
