Angels permeate stories in the Torah and the Bible.
They are expounded upon at length in the Talmud and later commentaries. There are archangels like Gabriel and Michael and Raphael and Uriel. They are bearers of God's strength and might and healing. There are minor angels like Shalgiel and Dubbiel. One bad angel is Satan, the adversary, who puts humans to the test.
