'Poor' in the Bible

Blessed are the poor in spirit: for theirs is the kingdom of heaven.

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

Jesus said unto him, If thou wouldest be perfect, go, sell that which thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, follow me.

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

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