It is Peter's angel

[tonychanyt]

An angel of the Lord took Peter out of the prison and he immediately went to see his brothers in Acts 12:

13 And when he knocked at the door of the gateway, a servant girl named Rhoda came to answer. 14Recognizing Peter’s voice, in her joy she did not open the gate but ran in and reported that Peter was standing at the gate. 15They said to her, “You are out of your mind.” But she kept insisting that it was so, and they kept saying, “It is his angel!”

What was Peter's angel?

Ellicott explained:

The language expresses the common belief of the Jews, that every true Israelite had a guardian angel specially assigned to him, who, when he appeared in human form, assumed the likeness of the man whom he protected.
