'Angels of God' in the Bible

And he dreamed, and behold a ladder set up on the earth, and the top of it reached to heaven: and behold the angels of God ascending and descending on it.

And Jacob went on his way, and the angels of God met him.

Rejoice, O heavens, with him, and let all the angels of God worship him. Rejoice, O nations, with his people, and let all the angels of God strengthen themselves in him. For he will avenge the blood of his sons, and render vengeance to his enemies, and will recompense them that hate him, and will cleanse the land for his people.
