To fetch about this form of speech hath thy servant Joab done this thing: and my lord is wise, according to the wisdom of an angel of God, to know all things that are in the Earth. 2 Samuel 14:20
These types of angels are mentioned in the Bible:
3) the four living creatures and
4) elect angels.
Michael the archangel, whose name means “”who is like unto God?” seems to be the angelic leader.
Angels are represented throughout The Bible as spiritual beings intermediate between God and Man: “You have made him [Man] a little less than the angels …” Psalms 8:4–5.
God lets angels know about much of what happens in the universe, including in people’s lives. Angel knowledge is extensive because they carefully observe and record the choices that human beings make, as well as hear people’s prayers and respond to them.
