'Angels of God' in the Bible

“I say to you, whoever declares openly and confesses Me before men [speaking freely of Me as his Lord], the Son of Man also will declare openly and confess him [as one of His own] before the angels of God.

But he who denies Me before men will be denied in the presence of the angels of God.

In the same way, I tell you, there is joy in the presence of the angels of God over one sinner who repents [that is, changes his inner self—his old way of thinking, regrets past sins, lives his life in a way that proves repentance; and seeks God’s purpose for his life].”
