Do you see a pattern here?  Note what Paul does with this material:

Romans 9:17 (ESV)

For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.”

God raised him up for one purpose:  To put Him down to glorify Himself.   God sometimes creates calamity and hardens hearts so that He can be glorified in His plans.
