Great correlation

The correlation you do is the correct thing to do with the hints and metaphor of the Old Testament. As you do more or it, the hidden narrative becomes more distinct.

The Old Testament hidden pictures are like transparencies. you stack them all on top of each other to get a single picture of Christ. The final picture is revealed in the New Testament and guides the construction of the transparencies, like assembling a jig saw puzzle and looking at the picture on the box.

The final picture is always of Christ. Things which happen after the cross point back to it. So Paul is not the target, just another transparency from the New Testament pointing to Christ.

All the examples which do not directly speak of Christ are transparencies. Cool digging!
