'Angels' in the Bible

And he was in the waste land for forty days, being tested by Satan; and he was with the beasts; and the angels took care of him.

Whoever has a feeling of shame because of me and my words in this false and evil generation, the Son of man will have a feeling of shame because of him, when he comes in the glory of his Father with the holy angels.

When they come back from the dead, they do not get married, but are like the angels in heaven.

And then he will send out the angels, and will get together his saints from the four winds, from the farthest part of the earth to the farthest part of heaven.

But of that day or that hour no one has knowledge, not even the angels in heaven, or the Son, but the Father.
