Gabriel (Meaning, God is mighty)
Footnote: Gabriel is an angel, the heavenly messenger God used to explain Daniel’s visions (9:21). He also announced the birth of John the Baptist (Luke 1:11) and the Messiah (Luke 1:26).

Daniel 8:16 ...”Gabriel, tell this man the meaning of the vision.” [Gabriel looks like a man. Daniel was terrified and fell prostrate. Gabriel spends most of the chapter explaining the vision concerning the time of the end, the distant future.]

Daniel 9:21-22 while I was still in prayer, Gabriel, the man I had seen in the earlier vision, came to me in swift flight about the time of the evening sacrifice. He instructed me and said to me, “Daniel, I have now come to give you insight and understanding.”

Luke 1:11 Then an angel of the Lord appeared to him, standing at the right side of the altar of incense. When Zechariah saw him, he was startled and was gripped with fear. But the angel said to him: “Do not be afraid, Zechariah; your prayer has been heard....”

Luke 1:19 The angel answered, “I am Gabriel. I stand in the presence of God, and I have been sent to speak to you and to tell you this good news.”

Luke 1:26-30 In the sixth month, God sent the angel Gabriel to Nazareth, a town in Galilee, to a virgin pledged to be maried to a man named Joseph, a descendent of David. The virgin’s name was Mary. The angel went to her and said, “Greetings, you who are highly favored! The lord is with you.” Mary was greatly troubled at his words and wondered what kind of greeting this might be. But the angel said to her, “Do not be afraid, Mary, you have found favor with God.

So Gabriel is an angel sent from God who is a messenger. Though the people are fearful, Gabriel says “Do not be afraid.”
