'Needy' in the Bible

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

Hear this, O ye that swallow up the needy, even to make the poor of the land to fail,

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