'Needy' in the Bible

The Lord says:I will not relent from punishing Israelfor three crimes, even four,because they sell a righteous person for silverand a needy person for a pair of sandals.

They trample the heads of the pooron the dust of the groundand block the path of the needy.A man and his father have sexual relationswith the same girl,profaning My holy name.

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.

For I have known -- many are your transgressions, And mighty your sins, Adversaries of the righteous, taking ransoms, And the needy in the gate ye turned aside.

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?
