Deuteronomy 24:19

They trample on the dust of the earth on the head of the poor, and deny justice to the oppressed; and a man and his father use the same maiden, to profane my holy name;

Forasmuch therefore as you trample on the poor, and take taxes from him of wheat: You have built houses of cut stone, but you will not dwell in them. You have planted pleasant vineyards, but you shall not drink their wine.
