'Poor' in the Bible

"Blessed are the poor in spirit, for theirs is the Kingdom of Heaven.

the blind receive their sight, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised up, and the poor have good news preached to them.

Jesus said to him, "If you want to be perfect, go, sell what you have, and give to the poor, and you will have treasure in heaven; and come, follow me."

For this ointment might have been sold for much, and given to the poor."

For you always have the poor with you; but you don't always have me.
