'Poor' in the Bible

they that pant after the dust of the earth on the head of the poor, and turn aside the way of the meek: and a man and his father go unto the'same maiden, to profane my holy name:

Hear this word, ye kine of Bashan, that are in the mountain of Samaria, that oppress the poor, that crush the needy, that say unto their lords, Bring, and let us drink.

Forasmuch therefore as ye trample upon the poor, and take exactions from him of wheat: ye have built houses of hewn stone, but ye shall not dwell in them; ye have planted pleasant vineyards, but ye shall not drink the wine thereof.

Hear this, O ye that would swallow up the needy, and cause the poor of the land to fail,

that we may buy the poor for silver, and the needy for a pair of shoes, and sell the refuse of the wheat?
