You really can't make this up.

Jakob wrestles with an entity that is afraid of the sun coming up and by holding it he forces it to give him a blessing, in exchange for letting it go before the sun comes up.

The entity agrees and gives Jakob the new name Israel (struggles with God).

Now sure, you can interpret this entity as God and therefore Jakob struggled with God, but you can also interpret this being that is afraid of the dawn and can be wrestled down as some kind of demon.

And by making a deal with this demon, Jakob becomes someone who "wrestles with God".
