Genesis 32:
>24 So Jacob was left alone, and a **man** wrestled with him till daybreak.
>
>28Then the man said, “Your name will no longer be Jacob, but Israel, because you have struggled with **God** and with humans and have overcome.”
>
>29 Jacob said, “Please tell me your name.”  
But he replied, “Why do you ask my name?” Then he blessed him there.  
>
>30So Jacob called the place Peniel, saying, “It is because I saw **God** face to face, and yet my life was spared.”

Hosea 12:
>3In the womb he [Jacob] grasped his brother’s heel,  
and in his vigor he wrestled with **God**.  
4a Yes, he struggled with the **angel** and prevailed;  

Was this angel a person in the Godhead? 

Please note that I am not arguing for or against the doctrine of trinity. I merely assume its definition without approval or disapproval.
This is NOT a question on trinity.
