'Angels' in the Bible

And he was in the wilderness forty days tempted of Satan; And he was with the wild beasts; And the angels ministered unto him.

For whosoever shall be ashamed of me and of my words in this adulterous and sinful generation, the Son of man also shall be ashamed of him, when he cometh in the glory of his Father with the holy angels.

For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as angels in heaven.

And then shall he send forth the angels, and shall gather together his elect from the four winds, from the uttermost part of the earth to the uttermost part of heaven.

But of that day or that hour knoweth no one, not even the angels in heaven, neither the Son, but the Father.
