'Poor' in the Bible

Why was not this ointment sold for three hundred shillings, and given to the poor?

Now this he said, not because he cared for the poor; but because he was a thief, and having the bag took away what was put therein.

For the poor ye have always with you; but me ye have not always.

For some thought, because Judas had the bag, that Jesus said unto him, Buy what things we have need of for the feast; or, that he should give something to the poor.
