'Powerless' in the Bible

Those who trample the heads of the powerless into the dust of the ground and turn aside the way of the destitute, a man and his father {have sexual relations with} the same girl, so that [they] profane my holy name.

Hear this word, [you] cows of Bashan who [live] on the mountain of Samaria, who oppress the powerless, who crush the poor, who say to their husbands, "Bring [something] so that we may drink!"

{That we can} buy [the] powerless with silver and [the] poor for the sake of a pair of sandals, and we can sell the waste of the grain?"
