'Angels' in the Bible

For, I think, God has exhibited us apostles last of all, as condemned to death, because we have become a spectacle to the world and to angels and to people.

Do you not know that we will judge angels, not to mention ordinary matters?

Because of this, the woman ought to have [a symbol of] authority on her head, on account of the angels.

If I speak with the tongues of men and of angels, but do not have love, I have become a ringing brass gong or a clashing cymbal.
