The name Michael comes from the Hebrew phrase mi-ke-el which means: who is like God?
The name Gabriel come from the Hebrew root geber which means man, plus el, the shortened form of elohim or God. Hence Gabriel can mean: Gods has shown himself mighty.
The name Raphael comes from the Hebrew verb rapha, which means: to heal. Plus the divine name el, it become: God heals.
In the Sacred Scriptures the name Raphael refers only to the angel of healing who was sent to cure the blindness of Tobi, the father of young Tobiah, and to expel the demon Asmodeus (Tb 3:17). Gabriel also appears to guide Tobiah through a series of fantastic adventures which leads to a happy ending for all concerned.
Each of these three archangels performs a different mission according to the Bible: Michael protect, Gabriel explains, Raphael heals and guides. In reference to them, with the entire Church let us repeat today’s Opening prayer: “God our Father, in a wonderful way you guide the work of angels and humans. May those who serve you constantly in heaven keep our lives safe from all harm on earth. Amen.”
