I am not aware David did any of this, I have not read David recently so I do not recall this. David certainly did have a very important place in history but nonetheless, Jesus said something that might go in the same direction you are thinking;
Jhn 14:12 Verily, verily, I say unto you, He that believe on me, the works that I do shall he do also; and greater
works than these shall he do; because I go unto my Father.
Peace
