Who or what is an "undeserving poor"?

Iffen you even pretend to Christianity some cat from Nazareth said some things about them a couple or so years back, iffen I 'member aright. Like Luke 14:13 and Matthew 23:23. They fergit all them sick and even dead dudes The Naz fixed up fer free. Iffen The Naz kin fix folks up fer free we could all kinda chip in and help everbody, no? Then agin, maybe they ain't as Christian as they pertend ta be. Kinda like them folks who washed the outside of the cup and skipped in inside.
