AMO 2:6

6 Yahweh [also] said this: “[I will punish the people of] Israel because of the many sins [that they have committed]; I will not change my mind about punishing them, because they sell righteous [people] to get [a small amount of] silver; they sell poor [people, causing them to become slaves], getting for [each of] them [only the amount of money with which they could buy] a pair of sandals.
