'Angels of God' in the Bible

they neither marry nor are given in marriage, but are as the angels of God in heaven.

Fear not therefore: ye are of more value than many sparrows. And I say to you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God.

But he that denieth me before man, shall be denied before the angels of God.

Thus, I say to you, there is joy in the presence of the angels of God, over one sinner that repenteth.

Verily, verily I say to you, Hereafter ye shall see the heaven opened, and the angels of God ascending and descending on the Son of man.

And again, When he bringeth in the first begotten into the world, he saith, And let all the angels of God worship him.
